Bloon

Bloons are the main "enemies" in the Bloons Games.

In Bloons and its sequels, Red, Blue, Green and Yellow (and also Pink in Bloons 2 Spring Fling) will pop with one hit, no matter which color. Some bloons also activate special abilities.

In the Bloons Tower Defense Games and Bloons Super Monkey, Bloons come in different layers, taking multiple hits to pop them. Bloon is a play/pun on the word Balloon, and as such Bloons resemble balloons in the games Bloons appear in.

As of January 2016, there are 101 different types of bloons.

Bloons series
In the games of Bloons series, there are 23 Bloon types, and some Bloons also have special effects, like exploding when popped or dropping a spiked ball when popped. Usually, they get popped in one hit regardless of type or color. Other effects include providing an extra dart to throw, launching eight tacks in all directions when popped, and freezing bloons when popped. Later in the Bloons series, there are also bloons that require multiple hits to pop, like the Helium Bloon which floats up after being touched once, then it can be touched again before popping.

Normal bloon
Takes one hit to pop and has no special effects before or after popping. It can have the following colours:


 * Red, green, blue or yellow in Bloons, More Bloons, Even More Bloons, Bloons Junior, Bloons Insanity, Bloons 2, Bloons 2 Christmas Pack, Hot Air Bloon and all the Bloons Player Pack Games.
 * Green, yellow or pink in Bloons 2 Spring Fling.

Tack Bloon
Shoots tacks in 8 directions upon popping. Each tack can pop one layer of bloon and pop up to three bloons at once. They can dodge Rubber Blocks but not Metal Blocks and their effect will stop upon touching a Tile Block or Ceramic Block. This bloon appears in every game in the Bloons series. It is represented by a pink color with a tack on it, a mistletoe berry with leaves in Bloons 2 Christmas Pack, or a rose in Bloons 2 Spring Fling.

Triple Dart Bloon
Upon popping, it will allow the monkey to shoot three darts at once at the next shot. The closer the mouse is to the monkey, the more darts' spread will be. Before Bloons 2, if the player pops this bloon along with a Boomerang Bloon, the next shot will consist of two darts and a boomerang; if the player pops more than one of them, the next shot will consist of an extra dart; after Even More Bloons, if the player holds the mouse and meanwhile another Triple Dart Bloon gets popped, the player can shoot three darts for two turns.

Ice Bloon
Upon popping, it freezes all bloons surrounding it (in a 7x7 range except the four bloons in the corner of that range) except for other Ice Bloons. Frozen bloons can't be popped unless Pacman eats them, a Lightsaber Bloon pops them, or a Bomb Bloon causes them to explode. If a dart goes over it, the dart will bounce. Pacman will disappear if it eats this bloon. It is represented by its white and light blue color.

Bonus Dart Bloon
Upon popping, it gives an extra dart. It is represented by a purple color with a star on it, or a gift in Bloons 2 Christmas Pack.

Boomerang Bloon
Upon popping, it will allow the monkey to shoot a boomerang, at the next shot, instead of a dart. The boomerang covers a 3x1 area (or 1x1 after Bloons 2). It is represented by a greenish color with a boomerang on it. Before Bloons 2, if the player pops this bloon along with a Triple Dart Bloon, the next shot will consist of two darts and a boomerang; if the player pops more than one of them, the next shot will consist of an extra dart; after Even More Bloons, if the player holds the mouse and meanwhile another Boomerang Bloon gets popped, the player can shoot a boomerang for two turns.

Bomb Bloon
Upon popping, it causes an explosion which covers a 7x7 area except for the bloons in the corner of that area. The explosion will pop every bloon, even frozen ones, and will destroy Tile Blocks and damage Ceramic Blocks. The dart stops upon popping a Bomb Bloon, as well as Pacman. Every bloon will have its effects negated. It is represented by its red color with a bomb on it (or an egg in Bloons 2 Spring Fling).

Pacman Bloon
Releases Pacman upon popping, which can be moved by using the keyboard arrow keys. It can destory Tile Blocks, pop frozen bloons and damage Helium Bloons. Pacman will disappear after a while, or if it pops a Bomb Bloon or Ice Bloon. It is represented by a dark green color with Pacman on it. If this bloon gets frozen, it won't appear to be frozen, but it can only be popped by other things that can pop frozen bloons. Also, if it gets popped, music "representing" Pacman game can be heard until Pacman disappears. This bloon no longer appears as of Bloons 2 due to copyright reasons.

Spikey Bloon
Upon popping, a spike will fall down popping bloons along the way. If there's a Rubber Block, the spike will bounce on it. The spike will disappear if it destroys more than five Tile Blocks, if it bounces too much times on Rubber Blocks, if it hits a Metal Block, if it touches more than one frozen bloon or if it pops a Bomb Bloon. It is represented by an orange color with a spike on it.

Lightsaber Bloon
Upon popping it releases a sword that covers a 9x1 area (horizontally), which can pop frozen bloons as well. It pops bloons no matter if there are blocks surrounding the popping area. It is represented by a dark blue color with a sword on it. This bloon was introduced in More Bloons and it no longer appears as of Bloons 2 due to copyright reasons.

Helium Bloon
Normally, it's covered in a jar. After destroying the jar, it will raise up, and then it can be popped. Even if it gets frozen during a flight, it will still raise up. The bloon only stops raising if there's a block or another bloon on top of it. The bloon can also be popped slightly off-screen. This bloon was introduced in Even More Bloons and it no longer appears as of Bloons 2.

Bee Bloon
Upon popping it releases a swarm of bees which can be moved by using the mouse. They disappear after a while and they die after touching a block. It is a black and yellow bloon and it only appears after Bloons 2.

Spawning Bloon
This bloon has three layers (green, then pink, then yellow) and they can appear as green and pink, while yellows are the "equivalent" of a normal bloon. Therefore, these bloons require multiple hits to pop. They are transparent and they are green, pink or yellow depending on their layer and they only appear after Bloons 2.

Bloom Bloon
This bloon spawns 7 more bloons (6 yellow ones placed in an hexagon form, and 1 red bloon at the centre), and thus requires multiple hits to pop. If a Bomb Bloon pops it, it won't spawn anything and strangely, it will count as only one bloon popped. It is represented by a green color with a flower on it. It only appears after Bloons 2.

Monkey Ace Bloon
Upon popping, it will allow the monkey to summon a Monkey Ace from the right or left by using flags. There will also be an arrow moving up and down, requiring the player to time their Monkey Ace correctly to summon them in the place they want. If the Monkey Ace hits a block, it will crash and fall down using a parachute. If the Reverse Gravity Bloon is activated, the plane will raise up. It is represented by a blue color with a target symbol (a dark blue circle, a white circle and a red dot at the centre) on it. It only appears after Bloons 2.

Reverse Gravity Bloon
Upon popping, it reverses the gravity. Darts and spikes will disappear at the top instead of bottom. If it is popped while gravity is reversed, it will revert the gravity back to normal. It is represented by a white color with various black circles on it. It only appears after Bloons 2.

Camouflage Bloon
This bloon becomes visible and invisible, pulsing in and out slowly. It can only be popped when very visible. When invisible, it won't be affected by anything, including Bomb Bloons and Ice Bloons. It is represented by a grey and green color with white patches in it. It only appears after Bloons 2.

Orange Bloon
This bloon gets popped in one hit and has no special effects. It only appears in Bloons Pop 3. It is unknown how strong this bloon would be if it appeared in the Bloons Tower Defense games.

Popcorn Bloon
This bloon only appears in Bloons Pop 3. After popping, it spawns popcorns all over the screen and it has no effects other than giving more points than usual.

Bloons Tower Defense series
The Bloons Tower Defense series introduces bloons in a different way to pop them. Unlike the Bloons in previous Bloons games, different colors of bloons contain different layers of bloons, represented by a term called Red Bloon Equivalent (shortly RBE). For example, a Red Bloon has an RBE of 1, but a Blue Bloon contains a red Bloon, meaning its RBE is 2. A Green Bloon contains a Blue Bloon which contains a Red Bloon, so its RBE is 3 and so on.

Bloon layers
Below are the different layers of Bloons in the Bloons Tower Defense:

Red Bloon
A red bloon. Red bloons are the weakest bloons in the game, and all stronger bloons contain this bloon. Red bloons, however, don't contain any bloons. After they are hit they just pop and if they reach the end it costs just 1 life. First bloon in the game. 

Blue Bloon
A blue bloon. RBE: 2 - contains 1 Red Bloon and, in BTD5, moves at the relative speed of 1.4 compared to Red Bloon. It is more than twice as hard to pop then a Red Bloon,

as it has 1 more layer, and is faster. First comes at round 3. Last seen on round 27 in BTD5 (14 in BTD4, 24 in BTD3, 23 in BTD2, 39 in BTD1). When reaching end it costs 2 lives. 

Green Bloon
A green bloon. RBE: 3 - contains 1 Blue Bloon, and, in BTD5, moves at the relative speed of 1.8 compared to Red Bloon (faster than blue). First comes at round 6. Last comes at round 49 in Bloons TD 5, 19 in BTD4, 24 in BTD3, 23 in BTD2, 39 in BTD1. When reaching end it costs 3 lives. 

Yellow Bloon
A yellow bloon. RBE: 4 - contains 1 Green Bloon, and, in BTD5, moves at the relative speed of 3.2 compared to Red Bloon (faster than green, but slower than pink). First comes at round 11 in BTD4 and BTD5. Last comes on round 34 in Bloons TD 5, 27 in BTD4, 42 in BTD3, 38 in BTD2, 49 in BTD1. when reaching end it costs 4 lives. 

Pink Bloon
A pink bloon. RBE: 5 - contains 1 Yellow Bloon, and, in BTD5, moves at the relative speed of 3.5 compared to Red Bloon (currently the fastest bloon, tied with Dark Dirigible Titan). Introduced in BTD4, first comes at round 15. Last comes on round 62 in Bloons TD 5 as a camo bloon, 45 in BTD4. when reaching end it costs 5 lives.

Note: All bloons of higher layer than Pink split into multiple lower layer bloons after being popped.

Black Bloon
A black bloon. This bloon, along with the white bloon, are the smallest bloons and are the two strongest bloons appearing in BTD1. RBE: 11 (9 in BTD3 and before then) - contains 2 Pink Bloons (Yellows in BTD3 and before then). Immune to explosions. In BTD5 it moves at the relative speed of 1.8 compared to Red Bloon (like a green). First comes at round 20. Last comes at round 41 in BTD4 and BTD5, 44 in BTD2 and 50 in BTD1. when reaching end it costs 11 lives. In BTD3 it appears in Freeplay Mode. 

White Bloon
A white bloon. This bloon, along with the black bloon, is the smallest bloon and is one of the two strongest bloons appearing in BTD1. RBE: 11 (9 in BTD3 and before then) - contains 2 Pink Bloons (Yellows in BTD3 and before then). Immune to being frozen. In BTD5 it moves at the relative speed of 2 compared to Red Bloon (Slightly faster than a black). First comes at round 22. Last comes at round 39, 44 in BTD4, 45 in BTD2 and 50 in BTD1. when reaching end it costs 11 lives. In BTD3 it also appears in Freeplay Mode. 

Camo Bloon
Not to get confused with the type of bloon added in BTD5, the camo bloon appeared in BTD4 and BTD4 Expansion, stayed in BTD4 iOS and disappeared when BTD5 came out, to get replaced with the camo bloon type. The camo bloon could not be detected by most towers but could be accidentally popped by anything, which meant that a rush of camo bloons could easily be detected with a single pile of tacks, as each of them contains 2 normal Pinks. RBE: 11, even though each makes you lose 9 lives only. Same speed as a Blue Bloon. First comes at round 24. 

Lead Bloon
A bloon encased in lead. RBE: 23 (19 in BTD3 and before then) - contains 2 Black Bloons. Lead bloons were introduced in BTD2 and appeared in every Bloons TD game since. Lead Bloons are immune to any sharp stuff. Certain upgrades like Red Hot 'Rangs and Depleted Bloontonium Darts allow the aforementioned attack types to pop Lead Bloons. They are also immune to the Super Monkey's Laser Vision and a Laser Cannon without a Depleted Bloontonium Darts upgrade. Unlike other Bloons, Lead Bloons are too heavy to be picked up by Tempest Tornadoes or Whirlwinds (But they still get popped by the tempest tornadoes).They can't be destroyed by most sharp objects without using Monkey Intelligence Bureau, with the exceptions such as white hot spikes. In BTD5 lead Bloons move at the same speed as a Red Bloon and M.O.A.B, and hence moves at a relative speed of 1. This bloon can be even slower than a Z.O.M.G with glue, arctic wind, permafrost, sabotage supply lines, etc. First comes at round 28. Last comes at round 75 in BTD4 and BTD5, 46 in BTD2. In BTD3 it also appears in Freeplay Mode. It costs 23 lives when it reaches the end of the track.

Zebra Bloon
A zebra pattern bloon. RBE: 23 - contains 1 Black and 1 White Bloon. Immune to explosions and freezing, however it can be frozen by the Absolute Zero ability. Additionally, having a Monkey Intelligence Bureau nearby allows any Ice Monkey in its radius to freeze Whites and Zebras. A tier 3 Ice Fortress will allow Ice Monkeys to freeze Whites and Zebras. In BTD5 Zebras move at the relative speed of 1.8 compared to a Red Bloon (like a green). First comes at round 26 (25 in BTD4). Last comes at round 65 in BTD5. In BTD4 it also appears in Freeplay Mode.

Rainbow Bloon
A rainbow bloon. Also the strongest bloon in BTD2. RBE: 47 (37 before BTD4, 6 in Bloons Super Monkey), contains 2 Zebra Bloons (BTD4-BTD5). In Bloons Tower Defense 2 and BTD3, it contains 2 Black Bloons & 2 White Bloons. In BTD5, Rainbow Bloons move at the relative speed of 2.2 compared to Red Bloon (faster than a green, slightly faster than a white, but slower than a yellow). First comes at round 12 of BTD2 and BTD3, but round 35 in BTD4 and BTD5. Last comes at round 82 in BTD5 as a camo regrowth, 50 in BTD2. In BTD3 and BTD4 it also appears in Freeplay Mode. 

Ceramic Bloon
Previously known as Brown Bloons, this is a bloon with a clay covering. If the clay layer is broken no money will be given until its children are popped. RBE: 104 in BTD5, 82 in BTD3, 16 in Bloons Super Monkey, contains 2 Rainbow Bloons. Takes 10 hits to break it open (38 in freeplay, 8 in BTD3). Although it can be hit by Glue Gunners, it won't be slowed down by them. It can be harmed by Corrosive Glue and all upgrades after it, however. In BTD5, ceramics move at the relative speed of 2.5 compared to Red Bloon (Slightly faster than a Rainbow Bloon). First comes at round 40 of BTD5, 31 in BTD3. When you pop the clay layer, it makes a different sound in BTD5 than in BTD3 and in BTD4. It also appears in Freeplay Mode. Costs 104 lives. 

Massive Ornary Air Blimp (M.O.A.B.)
A big blue blimp debuting in BTD3. RBE: 616 (458 in BTD3). Like all other MOAB-Class bloons, it is immune to freezing and cannot be glued. After 200 hits (140 in BTD3), it cracks open to reveal 4 ceramic Bloons. Fans often call it the Mother Of All Bloons (round 38 of BTD3 even tells you that it's not called the Mother Of All Bloons. "Either way, it brings great pain.") Speed: relative speed (to a red bloon) of 1. This is the only boss type bloon that has no eyes in BTD4 and up, not including Bloons Monkey City. The MOAB changes appearance through the series, In BTD3 it is surprisingly small, being a small blimp with 4 brown tiny circles representing the ceramic bloons. In BTD4, The MOAB is changed to a more reasonable size, has blue stripes to it instead of just mostly plain white, still has the ceramic bloons on its back. In BTD5 the blimp is now mostly blue with 3 white stripes (seen in picture) & does not have ceramic bloons exposed on its back anymore. First comes at round 46, 37 in BTD3. In BTD5 it would be first seen in round 46. It is fairly hard to defeat. 

Brutal Floating Behemoth (B.F.B.)
A giant red blimp making its first appearance in BTD4. It is the slowest bloon in BTD4, and the 2nd slowest in BTD5. RBE 3,164. After 700 hits (400 in BTD4), it gets popped and opens to reveal 4 M.O.A.Bs. Also called Big Fat Bloon by fans. The Brutal Floating Behemoth (B.F.B.) moves at a relative speed of 0.25 of the speed of a Red Bloon (slower than a Red). It contains 4 MOABs; the first BFB appears at round 60. Its appearance changes from BTD4 to BTD5 as well. In BTD4, the BFB is mostly white with red stripes, is noticeably larger than a MOAB (as it contains 4 of them) and its eyes are glowing red, like a vampire. In BTD5, the BFB retains its large size but is now mostly red with some white patches, its eyes don't glow anymore, the turbines are larger, and the Dart Monkey symbol on its back is in a different pose. 

Zeppelin Of Mighty Gargantuaness (Z.O.M.G.)
Nicknamed the Zoh My God or Zombie Oh My God by some players, the Z.O.M.G. is a giant black and green blimp debuted in BTD5. The Z.O.M.G. is a new MOAB Class Bloon type that appears only in BTD5, BMC and BTDB. It is a black blimp with a skull on top. When the Z.O.M.G is almost dead it has a Band-Aid on its skull symbol. The Z.O.M.G. is the strongest bloon in Bloons TD history, second only to the Bloonarius, Vortex, Dreadbloon, and Blastapopolus. The Z.O.M.G. appears on Round 85 (the final round on Hard difficulty) for the first time. The Z.O.M.G. contains 4 BFBs. It has an RBE of 16,656. After 4000 hits, it gets destroyed and opens to reveal 4 BFBs. Z.O.M.G. bloons are immune to many abilities, such as Monkey Pirates, Glue Striker, Absolute Zero, (And only takes 350 damage from Ground Zero and only takes 1000 damage from MOAB Assassin and Bloon Annihilation Ability). It's the second slowest bloon, moving at a relative speed of 0.18 of the speed of a Red Bloon (slightly slower than a B.F.B). It can hardly be immobilized by the Cripple MOAB of the Sniper Monkey, and Artillery Battery's Pop and Awe Ability, though easily destroyed by First Strike Capability. 

Dark Dirigible Titan (D.D.T.)


This is a blimp introduced in Bloons Monkey City. It has the properties of a black bloon, camo bloon, lead bloon, and a MOAB-Class Bloon. It spawns 6 Camo Regen Ceramic Bloons upon popping, which is after 350 hits (see BMC blimp health table). This means its children are almost as destructive as the D.D.T. It has a RBE of 924 (despite the fact that you lose 16,656 lives from it, like a ZOMG) and it moves the relative speed of 3.5 of a red bloon, being as fast as a Pink Bloon. D.D.T.s come in groups of 3 or more (in multiples of 3) in the Flash version of BMC. It's a black blimp with transparent and grey patches representing its abilities. Signal Flare from Mortar Towers, Monkey Engineer's Cleansing Foam, and the Anti-Camo Dust ability can remove the camo, although it will still look like it has its camo properties. <br style="clear:both" />

Bloonarius the Inflator
This is a boss blimp introduced in Bloons Monkey City. It only appears in certain events. It is the slowest bloon in existence, with a relative speed of 0.1. Its health changes depending on the level of the boss - from 2,000 at level 1 to hundreds of thousands at level 25. When its health reaches 3/4, 1/2 and 1/4, it will spawn a random bloon - this ranges from lead to ZOMG. The higher the stage, the stronger bloon it will summon every degrade. When it passes the exit, IF it passes the exit, the player will get an instant game over. However, the player may decide to attack again with City Cash, in which case the boss will have the same health as when it leaked the last time. If it goes back into hiding, however, when the player fights it next, it will have full health. <br style="clear:both" />

Vortex: Deadly Master of Air
It is the second boss bloon introduced in Bloons Monkey City. It appears in an event similarly to Bloonarius. It moves slightly faster than a ZOMG, at a relative speed of 0.2. The boss fight is similar to the Bloonarious battle and both have levels. However, Vortex does not summon a bloon on each time it gets degraded. Instead, it leaves a trail of smoke that stuns towers for a short time. The higher its level, the more health it has. It has less health at a given level than Bloonarius does. Vortex also has a special ability to stun all the nearby towers. Like Bloonarius, the player gets an instant game over if it passes the exit. <br style="clear:both" />

Dreadbloon: Armored Behemoth
It is the third boss blimp to be added in Bloons Monkey City. Like the other bosses, it appears in a limited time event and get stronger as it levels up. It moves at a relative speed of 0.15. The main difference between it and its predecessors is that it has properties of a lead Bloon, meaning it cannot be damaged by sharp objects, and shields itself with yellow rocks. It is weaker than both Bloonarius and Vortex. Dreadbloon looks a little bit like a ZOMG in terms of bodily color patterns; it has a nearly-black body with green parts in it. Like Bloonarius and Vortex, the player gets an instant game over if it passes the exit. <br style="clear:both" />

Blastapopoulos: Demon of the Core
Originally named as Blastopopoulos, it is the fourth boss blimp to be added in Bloons Monkey City. Just as with all of the other bosses, it appears in a limited time event and get stronger as it levels up. It moves at a relative speed of 0.25, which is as fast as a BFB. Though it is vulnerable to most anti-MOAB towers and upgrades, this boss has the ability to throw a fireball at the most expensive (determined by total cost, including placement and upgrades) tower on screen which stuns the targetted tower. Later on they can permanantly stun towers and/or shoot more fireballs. Blastapopoulos appears to have a red ZOMG blimp base plus added hot-red eyes, extra fins, and some lava around it. Just as with all other bosses, the player gets an instant game over if it passes the exit. <br style="clear:both" />

Bloons Super Monkey 2
This game introduces various new bloons never appeared before, and keep the bloons that appeared in the Bloons Tower Defense games except the Z.O.M.G, the D.D.T and the camo and regenerating properties.

Bomb Bloon
This bloons reappears in Bloons Super Monkey 2, and it only appears in stages 1-4 and 2-4. It keeps its Bloons series effects: it causes a little explosion popping the surrounding bloons. <br style="clear:both" />

Mini MOAB
This is a MOAB-class bloon that only appears in stages 1-5 and 2-5. It's a weaker version of the original M.O.A.B. It takes 100 hits to pop and it explodes in a cloud of Red to Yellow Bloons. Its only parent is the boss M.O.A.B appearing in stage 1-5 which releases 10 Mini MOABs. Normal Mini MOABs have no parents.

Golden Bloon
This bloon appears in every stage except 2-5, 3-4, 4-1 and 4-5. Only one appears for each stage. After being touched once, it starts flying at extreme speed all around the screen, releasing golden blops every time it gets touched. After 10 hits they release a power-up for the Super Monkey. If it stays on screen too much time, it will escape. This bloon is needed for getting Diamond Trophy. <br style="clear:both" />

Power-Up Bloon
This bloon appears in stages 1-4, 2-1, 4-2, 4-3 and 4-4. It's usually located at the center of a clump of bloons. When popped it spawns a power-up for the Super Monkey. It's a red bloon with a question mark on it.<br style="clear:both" />

Glass Bloon
This bloon appears in stage 2-2, 2-4, and every stage after 3-1. This bloon is a transparent white bloon that is immune to any tech weapon (laser, plasma, sun, doom energy, etc.) unless research is utilized. After popping, it spawns a Zebra Bloon. <br style="clear:both" />

UFO Bloon
This bloon appears in stage 2-4 and every stage after 3-1. This bloon has the characteristics of an UFO that can be green or purple. Green UFOs will appear certain times in the screen, stealing blops. They can be popped after three hits, and when hit, they will give the stolen blops again, if they didn't disappear. Purple UFOs, only appearing after stage 3-5, will instead chase the Super Monkey trying to steal blops quickly, but they get popped in a single hit.

Prickly Bloon
This bloon only appears at the end of stage 2-4. When popped, this bloon spawns darts in 8 directions (similarly to the Tack Bloon) popping bloons along their way. It's a grey bloon with spikes on it.

Calimari Blimp
This is a MOAB-class bloon that is originally covered in Black Bloons, Red Bloons as its eyes, and Glass Bloons as a sort of tentacles. After all the bloons have popped, the player can see the real appearance of the blimp. It's a greyish blimp with three blue eyes, which turn white at the fifth popping stage. It attacks the player with a red trail and "bumpers" made of Black and Glass Bloons which push the Super Monkey away. It only appears in stage 3-5 as boss.<br style="clear:both" />

Heavy Metal Bloon
This is a MOAB-class bloon covered in Lead Bloon gears and Black Bloons. It's a grey blimp made of metal, however it can still be popped by sharp objects. It also has a Shielded Bloon (sometimes called Lightning Shielded Bloon) surrounded by electricity which can not be popped that may be powering or controlling the bloon, and it releases a flame at the bottom. Sometimes it spawns huge groups of packed bloons and more Lead Bloon gears. It can shift Shielded Lead Bloons into many shapes to protect itself from Super Monkey.<br style="clear:both" />

Camo Bloons
In Bloons Tower Defense 4, the Camo Bloon was a unique bloon type of RBE 11 (the in-game RBE says 9), containing 2 Pink Bloons, and can be "accidentally" popped by towers without camo detection. In Bloons Tower Defense 5, however, any bloon lesser than a M.O.A.B. may have a camo attribute. Bloons Monkey City has the D.D.T., which is a fast-moving camo explosion-immune MOAB-class bloon. Any bloon with this attribute may only be targeted by certain towers unless under the influence of a Radar Scanner Monkey Village. First camo bloon comes at round 24 (it is a green in BTD5).

There are three types of tower that can pop Camos without upgrades: the Ninja Monkey, the Dartling Gun and the Spike Factory. Other towers may require upgrades to detect Camo Bloons, or require assistance of a Radar Scanner close by.

Regrowth Bloons
In Bloons Tower Defense 5, any bloon under the rank of a M.O.A.B. may have this attribute which causes them to gain back lost layers over time(hence its name )

. No layers over its original may be gained. Bloons on a higher tier than Pink may multiply. (A Black Bloon gets popped into 2 pinks, which turn into 2 blacks, which get popped into 4 pinks...) This caused a problem where players could get infinite amounts of money by using Tempest Tornado wizards to endlessly pop and blow back bloons which they regrowed into more bloons and had a strong defense in the back (like a Sun God) to avoid losing the game. This was called Regen Farming and was fixed in an update. It is still possible to do on Deluxe and iOS Versions.

A form of regen farming that does not exploit glitches or bugs is the use of Tempest Tornado and the Supply Drop ability. As long as the bloons are not completely destroyed and the round is dragged out so that the ability will continue to recharge, this will help players gain massive amounts of in-game cash easy.

Shielded Bloon
Shielded Bloons made their debut in Bloons Super Monkey 2's 1-4 stage. In the middle of the bloon is a lightning symbol. These bloons take several hits to pop their outer layer, before revealing non-shielded children. Super Monkey cannot move through these Bloons.

Trivia

 * Starting in BTD5, any bloon can be Regenerating and/or Camo, and only some upgraded towers like a Mortar Tower with Signal Flare, or a Monkey Engineer with Cleansing Foam, or other towers like a Monkey Sub with Submerge and Support (when submerged) can successfully de-camo a bloon.(Notice that if you have a tier 4 Sub Construction Yard it will also shock regrowth bloons into normal bloons). This does not apply to D.D.T, since it is one of the MOAB class, and there is no D.D.T without camo.
 * It is possible for a Red Bloon to be a Regrowth Bloon and not come from a bloon before it, even though it gets popped in one hit, although this can happen only in Sandbox Mode, in Daily Challenges, in Bloons TD Battles and in Bloons Monkey City.
 * Ceramic Regrowth, when popped, will not recover 1 of the Ceramic layers at the time. It'll just restore to a full Regrowth Ceramic. Also, semi-popped Ceramic Regrowth Bloons will not recover to an unpopped Ceramic Regrowth.
 * All MOAB-Class Bloons can be hit out of range of tower; this effect is more noticeable when dealing with stronger MOAB-Class Bloons such as the B.F.B. and the Z.O.M.G. The harder the blimp is to pop the bigger the range of the tower can hit it from. This may be due to the blimp being very large.
 * Ceramic Bloons and its descendants no longer split into multiple bloons in Freeplay Mode, but the number of hits to destroy a ceramic is increased to 38 hits. (Usually referred to as Super Ceramics)
 * Pink Bloons are tied with the D.D.T. as the fastest bloons in the whole BTD Series as of BMC.
 * According to the Round 38 Pre-Round Comment in BTD2, bloons are biodegradable.
 * On Bloons TD Battles you can add Regen or Camo to any MOAB-Class Bloon, it will not regenerate or make camouflage the layers and the full MOAB-Class Bloon, but when is popped until Ceramic Bloons the ceramics will be Camo or Regen, or both, depending what you added.
 * For example, you add Regen to a B.F.B and send it, then when it's popped to M.O.A.Bs they won't regenerate to 4 B.F.Bs, but when they are popped to Ceramic Bloons they will be Regen Ceramic Bloons, however they won't regenerate to M.O.A.Bs, apart from that, when the Ceramic Bloons loose layers they will regrow to full Ceramic Bloons. This applies to any MOAB-Class Bloon.
 * In Bloons TD 5, the bloons speed up after Round 103. For bloon health, see the table below.
 * Out of all 101 types, there are 24 that have the RBE of 1, and 28 that can have the RBE of 1.

In Bloons Monkey City after round 30, the bloon get a 25% increase in health and 5% increase in speed for each round.
 * The initial blimp health depends on what city you're on, see table below.
 * There is an official name for a large cluster of bloons, verified in Bloons Monkey City. Such a cluster is called a Bloon Rush.
 * In the pre-release Bloons Monkey City trailer, it states bloons as being "Rubbery" and "Annoyingly squeaky" and "Threatening the social fabrics of monkey society".
 * The name of bloon might have come from the name balloon which is pronounced as one syllable instead of two.
