You're about to attack the first area that has Camo Bloons in it. You should hold off attacking this tile until you're ready. A Centre Of Camo Countermeasures is required for most Monkey upgrades that can detect Camo Bloons.
~ Bloons Monkey City when the player is attacking a tile with Camo Bloons for the first time
Camo Bloons are very dangerous since most Towers cannot hit them. Any Bloon type can be a Camo, and so will all the Bloons that come out of that one. They can only be hit by Towers that can detect Camo Bloons, such as the Ninja Monkey. In an emergency, use Road Spikes to pop them.
IMPORTANT! Camo Bloon can't be affected by your Monkeys unless they have a way to detect them. For example Quincy can at level 5 and Dart Monkeys can with the Enhanced Eyesight upgrade.
~ First time encountered with Camo Bloons in BTD 6.
The Camo Bloon is a bloon that made its debut in Bloons TD 4. Its RBE is 11 (the game says it's 9, but it actually takes 11 hits to pop). They move at around the same speed as the Blue Bloon.
In BTD4, they are a type of Bloon which contain 2 Pink Bloons, making them about the same level of parenthood as the White Bloon and Black Bloon. The first Camo Bloons appear on Round 24.
In BTD5, Camo becomes a property of bloon along with Regrowth, meaning any bloon from a Red Bloon to a Ceramic Bloon can acquire Camo properties. MOAB-class bloons cannot be camos, nor can their children (though the D.D.T. is an exception along with bloons sent in BTDB Flash). They cannot be targeted by most towers. However, there are upgrades that can make surrounding towers and/or themselves able to see them, such as Sonar Beacon and Crow's Nest. In BTD5, Camo Bloons appear on Round 24, 33, 37, 42, 47, 53, 59, 62, 70, 78, and 82.
In BTD6, Camo Bloon properties return, but can also become paired with Regrow and/or Fortified properties too. Camo Bloons appear on round 24, 33, 36, 37, 42, 45, 47, 48, 51, 53, 56, 59, 62, 67, 70, 74, 78, 90 (with DDTs), 93 (DDTs only), 95 (with DDTs), 99 (Fortified DDTs only), and 100 (from the BAD).
Camo Bloons can only be detected by some monkeys, usually requiring some upgrades or a nearby tower that gives them that ability. It is necessary in both BTD4, and even more important in BTD5 and BTD6, as it is no longer possible to "accidentally" hit Camo Bloons in these games.
If another tower targets a Bloon and a Camo Bloon gets in the way, the Camo Bloon will be popped. If a tower with piercing projectiles targets a Bloon in front of a Camo Bloon, both will be popped. Usually, all you need is one set of Road Spikes or a Pineapple to set off a chain reaction. Camo RBE: 11 (BTD4), same speed as a blue.
The following towers and upgrades allow the tower and/or nearby towers to detect Camo Bloons:
In BTD5, Camo becomes a Bloon property: therefore their RBE can be from 1 to 104 unlike in BTD4. If a tower cannot see camo bloons, its projectiles will go straight through them without doing any damage to them. A camo bloon can also be Regrowth at the same time, making them very dangerous if you do not prepare, like in round 82.
The following towers and upgrades allow the tower and/or nearby towers to detect and also target Camo Bloons:
Only works if the ability is activated when the camo bloon is the strongest bloon on screen. Even then, it only pops one layer. It is not recommended to defend against camos in this way, due to its inefficient popping of camo.
BTD6 Camo Detection is similar to that of BTD5's. Several upgrades that help detect Camo are also available in BTD6, including the Radar Scanner upgrade. Alongside this, many more options are avalible to detect Camo, with nearly every tower having some way to combat Camo. Somehow, Glaive Lord in Bloons TD 6 can no longer detect Camo, though Camo Bloons can become popped by its rotating glaives.
Meteor attack can target Camo Bloons, but it is highly unreliable as it may target MOAB-class bloons instead, as well as the fact that the meteor attack is very slow. Not viable camo detection due to unreliability and very high cost.
Removes the camo property from all bloons in its range. Also possible to detect camo using Advanced Intel (Path 1, Upgrade 2), but there must be at least one other camo-detecting tower in range of the map's track to target camo bloons.
Allows the Mortar Monkey to pop Camo & remove Camo property from affected Bloons. Shattering Shells can also remove Regrow & Fortified property from Bloons up to & including a B.F.B., and remove the Camo property from Black Bloon properties, including D.D.T.s if the Paint Stripper Knowledge perk is active. Camo Blacks cannot be popped without a Monkey Intelligence Bureau, unless Mortar Monkey is further upgraded to Blooncineration.
Ezili can naturally see and attack Camo Bloons (including D.D.T.s), and can also strip all special properties of Bloons up to Ceramic Bloons at Level 9. In addition, her Sacrificial Totem ability can grant Camo detection to all towers in the totem's radius for a few rounds. Camo Purple cannot be popped or stripped of properties without a Monkey Intelligence Bureau.
This section is incomplete. You can help by adding more stuff here on this table.
11 hits are needed to pop the entire Camo Bloon in BTD4, yet one bunch of Road Spikes (10 spikes) can pop it.
Letting a Camo leak in BTD4 makes you lose 9 lives instead of 11, meaning letting the Camo's children out is actually slightly more dangerous than letting the Camo out itself, as leaking the Camo's children cost you 10 lives as opposed to 9.
In BTD5, Camo Bloons can be very dangerous, especially on Round 78, which contains a dense rush of Camo Ceramic Bloons.
In BTD6 however there are more ways to do it. Other than the Submerge and Support and Signal Flare, there are 4 more ways to reveal Camo Bloons, with 2 involving Magic monkeys, 1 involving a Hero, and 1 involving a power: Ninja Monkeys can with Counter-Espionage, Wizard Monkeys can with Shimmer, a Camo Trap can strip 500 Bloons (600 with the Bigger Traps perk), and a level 9+ Ezili can with her basic attack, alongside stripping Regrowth and Fortified properties off the target.
The first Camo Bloon appears in Round 24 in all installments when Camo Bloons are added where such a bloon appears. In BTD5 and BTD6, the Bloon is Green.
In BTD5, this is also the round with the lowest RBE of only 3. However, in BTD6 it has actually more RBE than that due to the 40 Blues.
In BTD4, upgrades of towers that help their own Camo-detection can also make other towers around those radii to be granted ability to see Camo Bloons, but this is no longer the case with any tower except Monkey Village and Monkey Buccaneer with a Tier 3 Pirate Cove in BTD5 and Bloons Monkey City.
In Bloons Monkey City, Camo Bloons can appear in assaults as well as tiles with the maximum bloon type Rainbow Bloon or stronger.
The camo rounds in BTD5 Beginner difficulty are 24 (1 Green Camo), 33 (20 Yellow Camo), 37 (7 White Camo), and 42 (The deadliest, 8 Rainbow Camo along with 8 Rainbow Regrow).
