Dark Dirigible Titan (DDT)

"What's a DDT Bloon you ask? Like a MOAB crossed with a Pink, Camo, Black and Lead Bloon. In all the bad ways."

- Round 90 Pre-Round Comment in BTD 6

The Dark Dirigible Titan (DDT) is a MOAB-Class Bloon that debuted in Bloons Monkey City and subsequently appeared in every Bloons TD game since. With the properties of Camo, Lead, Pink, and Black Bloons, the DDT is immune to Sharp, Explosive, Freeze, and non-Camo detecting attacks. It also moves at the speed of a Pink Bloon, making it the fastest Bloon in the game. As such, the DDT is considered by many players to be the most dangerous Bloon in BTD.

The round 90 DDT has 480 health, more than the base MOAB, but less than a BFB. However, the game considers the DDT and fortified DDT to be stronger than fortified ZOMGs and weaker than BADs for target priority considerations. The DDT has 400 health (300 in BMC), excluding health ramping, and will release 4 Camo Regrow Ceramics (6 Camo Regrow Ceramics in BMC) once popped. The DDT moves at the speed of a Pink Bloon in BMC, the speed of slightly more than a Ceramic Bloon in BTD6, or the speed of a Green Bloon in Bloons Adventure Time TD.

Just like all MOAB-class bloons, the DDT can be greatly damaged by attacks that inflict extra damage to MOAB-class bloons compared to normal bloons. However, the DDT has many more properties that make it far more resilient to typical anti-MOAB-class defenses. DDTs will naturally have the Camo property, making them invisible to most towers. Lead properties make them invulnerable to many types of sharp projectiles, while the Black properties make them unable to be damaged by explosives. On top of that, DDTs move much faster than most MOAB-class bloons.

DDTs in BTD6 start off with 480 health on their debut round on Round 90, and gain extra health in later rounds, due to Freeplay ramping, and when tested on Sandbox Mode starting from Version 24.0 it will have its Round 90 health and speed ramping.

The health of a DDT can be determined through multiple damage stages. Every 1/4 of the DDT's health, 100 by default, it will appear more damaged. These are usually cracks that appear on the blimp's skin. The DDT will appear more and more worn out until it is fully destroyed.

Details
It has the appearance of a dark-gray blimp with various black and transparent patches, which resemble its abilities. The DDT has the properties of the Lead, Black, and Camo Bloon (except on BMC Mobile and Steam, where it only has camo properties), being immune to sharp and explosive damage, while also being undetectable by most towers unless they are under the radius of a Monkey Village with Radar Scanner. It is also very fast, being the 4th fastest bloon in the game, and is significantly faster than all other MOAB-Class Bloons.

Leaking the DDT in Bloons Monkey City will cause a player to lose 16656 lives, equivalent in RBE to a ZOMG, and not its RBE of 924. In Bloons TD 6, leaking the DDT will cause the player to lose 816 (1,256 if fortified) lives, which is less than a BAD, ZOMG, BFB, or a DDT in BMC.

After taking 400 damage, it releases 4 Camo Regrow Ceramic Bloons in BTD6. In Bloons Monkey City, DDTs originally release 6 Camo Regrow Ceramic Bloons after taking 300 damage. DDTs first appear in Round 90 in BTD6. In the Flash version of BMC, DDTs can be sent or researched for Monkey v Monkey through the Armored Stealth Silo.

The combination of immunities makes a DDT difficult to damage, as most of the popular anti-M.O.A.B. towers need Monkey Village support to overcome the DDT's superior abilities. On top of this, in BTD6, it can appear in a Fortified form which first appears in Round 99, doubling its health and making it even stronger. DDTs appear in large groups (usually in groups of 3 in BMC) which can be problematic as they could skim through an improper defense.

Bloons Monkey City
DDTs make their first appearance on this game. They will guarantee appear on a tile marked "DDT", but can also appear on Assault tiles (Flash) or Bloon Strategy tiles (Mobile/Steam).

Bloons TD 6
DDTs will naturally only spawn on rounds past Round 80, more specifically Round 90 (Round 88 on ABR). Their children spawn Camo Regrow Super Ceramics when popped. DDTs move at 2.75x the speed of a Red Bloon, slightly more than the speed of a Ceramic Bloon.

They naturally appear in Impoppable and CHIMPS mode, more specifically appearing on Rounds: 90, 93, 95, and 99.

Round 99 has 9 Fortified DDTs appearing in shorter intervals.

In a normal game, DDTs will appear in packs of 3. Round 90 has 3 DDTs, Round 93 has 6 DDTs, round 95 has 30 DDTs and round 99 has 9 fortified DDTs. On round 100, 3 DDTs will spawn when the BAD is popped.

The round with the largest amount of DDTs is Round 138, featuring 126 DDTs (of which 81 are Fortified).

Bloons Adventure Time TD
DDTs will spawn on Impoppable on rounds 69, 71, 73, (fortified) and 75 (as BAD children).

Bloons TD Battles 2
DDTs make a comeback in this game, and can be sent for $2,500 per Spaced DDT or $6,000 per 3 Grouped DDTs. Sending a DDT has an income penalty of 300 Eco, while sending out 3 Grouped DDTs reduces eco by 600. Spaced DDTs unlock on Round 26, while Grouped DDTs unlock on Round 28.

Natural DDTs first spawn on Round 45. Subsequent natural DDTs appear on later rounds.

BMC
Due to their Lead and Black Bloon properties, DDTs cannot be damaged by sharp or explosive attacks without Monkey Intelligence Bureau.

In BMC Mobile and Steam, they don't possess Lead or Black property making them significantly less dangerous outside of their speed and its children.

The best defense against DDTs involves the use of Monkey Intelligence Bureau, the only way to make towers that normally pop only one of Lead or Black to pop both.

BTD6
The BTD6 iteration of the DDT inherits its immunities from BMC.

As in BMC, the only method to make virtually every upgrade damage DDTs is to use Monkey Intelligence Bureau, assuming that the tower already can hit MOAB-class bloons directly. However, more buffs as well as debuffs exist to also make DDTs more vulnerable to damage. For instance, Acidic Mixture Dip, Gwendolin's Heat-It-Up and Admiral Brickell's Level 5+ abilities give lead-popping. Similarly, Striker Jones Level 5+ grants a 50% chance for any explosives that cannot already damage Black Bloons to deal damage to Black Bloons, including DDTs. DDTs first appear on Round 90, with a particularly dangerous rush of 30 DDTs on Round 95. They also appear on Rounds 93 and 99, with their fortified versions appearing on Round 99.

Some upgrades, such as the Spectre or the projectiles of an Apache Dartship, have projectiles that can pop normal Leads and normal Blacks with two types of projectiles with different damage types, usually darts and bombs. However, DDTs cannot be damaged by darts or bombs without special upgrades. On the other hand, Heroes such as Gwendolin Level 4+ or Level 5+ Striker Jones can temporarily grant DDT-popping power to specific projectile types. Heat it Up temporarily allows sharp projectiles to pop DDTs, while Striker's Level 5 gives explosive projectiles a 50% chance to damage DDTs. However, Level 19+ Striker Jones allows all explosive projectiles to damage DDTs, as the Black Bloon property is completely nullified at that level.

However, most abilities that can hit MOAB-class bloons can affect DDTs, provided that the tower with the ability has Camo detection of some sort. This includes projectiles that normally wouldn't hurt DDTs, with the most significant example being that all bomb-based abilities (including Ground Zero, MOAB Assassin, First Strike Capability) are capable of hurting DDTs without their main attacks being able to pop Black Bloons, although both the MOAB Assassin and MOAB Eliminator abilities require Camo detection to affect DDTs.

Besides towers that cannot affect MOAB-class, the following towers cannot damage DDTs independently, provided they are given Camo detection (or if the DDT has its Camo properties removed):


 * Most sharp projectiles and other sharp attacks:
 * Darts (except Sky Shredder, Flying Fortress, Carrier Flagship)
 * Arrows (except Crossbow Master arrows, since Level 7+ Quincy's explosive arrows cannot damage DDTs)
 * Tacks without Hot Shots (except for Super Maelstrom)
 * Spikes without White Hot Spikes and subsequent upgrades
 * Grapes without Hot Shot
 * Wizard Monkey's main bolt (except Arcane Spike and Archmage)
 * Shurikens
 * Caltrops
 * Obyn's Brambles below Level 16
 * Bullets (from Sniper Monkey) without Full Metal Jacket or Supply Drop and above
 * Shrapnel from the Shrapnel Shot upgrade without Full Metal Jacket or above
 * Nails and default sentries from Engineer Monkey
 * Spike-O-Pult balls (except for Juggernaut and Ultra-Juggernaut) or Sentry Expert's Crushing Sentries
 * Buckshot projectiles from Buckshot and above, including from Bloon Exclusion Zone
 * Swords from Sauda, except with her abilities or once she reaches Level 13+.
 * Fragments from Frag Bombs but not explosions
 * Non-plasma lasers:
 * Laser Blasts
 * Sentry Expert's Energy Sentries
 * Apache Prime's laser weapons (but not plasma weapons or razor rotors)
 * Laser Cannon lasers
 * Most non-ability explosives, unless affected by Level 19+ Striker Jones:
 * Bomb Shooter bombs without Frag Bombs or its later upgrades (except MOAB Assassin ability and MOAB Eliminator ability, Bloon Crush, and MOAB Eliminator main attack)
 * Mortar Monkey explosions (except Blooncineration special napalm, Heavy Shells, The Big One, and The Biggest One)
 * Spiked Mines explosions and Spiked Mines napalm
 * Ballistic Missile's missile attacks
 * Burny Stuff napalm effects from Mortar Monkey explosions (except Blooncineration)
 * Explosive Fireballs from Wizard Monkey
 * Sentry Expert's Boom Sentry
 * Most towers with combinations of sharp projectiles and explosive projectiles:
 * Fighter Plane darts and anti-MOAB missiles (except for Sky Shredder)
 * Bomber Ace darts and bomb arrays, but not Ground Zero ability or Tsar Bomba bomb arrays
 * Spectre darts and bombs (but not Flying Fortress)
 * Apache Dartship projectiles (but not the Razor Rotors)
 * Sentry Expert's sentries (Crushing, Energy, Boom, Cold)
 * MOAB Shove, Comanche Defense, and Comanche Commander's dart attacks and missile attacks
 * Quincy's ordinary arrows and his explosive arrows, including his abilities.
 * Captain Churchill's main attacks without the Armor Piercing Shells ability.
 * Level 10-19 Etienne with the UCAV ability active
 * Certain abilities:
 * All dart-based abilities
 * Turbo Charge and Perma Charge without Red Hot Rangs
 * Brambles without Level 16+
 * Both of Quincy's abilities
 * Benjamin's Syphon Funding ability
 * Etienne's activated UCAV ability below Level 20
 * Snowstorm without the Cold Snap upgrade or any other lead-popping source

BATTD
DDTs have propellers, and they appear in Rounds 69, 71, and 73. On round 73, the DDTs are fortified.

Similar to BTD6, they have the properties of Camo, Lead, and Black. However, they move at the speed of a Green Bloon, ignoring any added speed modifications. This still makes them the fastest of the MOAB Class Bloons.

Even if its camo property is stripped, it still has the same texture.

Children
In Bloons Monkey City, the DDT contains 6 Camo Regen Ceramic Bloons, which contain 12 Camo Regen Rainbow Bloons, which contains 24 Camo Regen Zebra Bloons, which contain 48 Camo Regen Black and White Bloons. Those contain 96 Camo Regen Pinks, Yellows, Greens, Blues, and finally, Reds. In total, the DDT contains a total of 570 Bloons (571, including itself). In the case of Bloons TD 6, the DDT contains 4 Camo Regen Ceramic Bloons, which contain 4 Camo Regen Rainbow Bloons due to freeplay Ceramics release only 1 Rainbow, which contain 8 Camo Regen Zebra Bloons, which contain 16 Camo Regen Black and White Bloons. Those contain 32 Camo Regen Pinks, Yellows Greens, Blues, and finally, Reds. In total, the DDT contains 260 bloons (261, including itself). The DDT is extremely dangerous, and it should not be fought until a strong defense is well prepared. DDTs are also the only MOAB-Class Bloons to have standard bloon abilities such as Camo.

Bloons Monkey City
There is some debate regarding whether or not the DDT is actually stronger than the ZOMG. Technically, it is stronger than a ZOMG because towers set to prioritize "strong" bloons will shoot DDTs before ZOMGs if both are within range. The ZOMG is stronger in hitpoints than the DDT and is immune and resistant to most abilities like M.O.A.B. Take-Down (while the DDT can be taken down by most abilities), but the DDT has more abilities than the ZOMG. Essentially, what the ZOMG lacks in abilities it makes up for by using brute strength and resilience and what the DDT lacks in strength it makes up for by hybridizing abilities and immunities. It is also worth noting that ZOMGs appear on (most) DDT tiles as well, so it is important to prepare for both.

Bloons TD 6
It is also debatable whether the DDT is actually stronger than the ZOMG Technically, a regular DDT is not stronger, as the ZOMG is targeted first before the DDT However, target settings will generally target Fortified DDTs over ZOMGs in most cases. Certain upgrades may act differently on Dark Dirigible Titans, with a strength spanning from between M.O.A.B. to ZOMG, if not sometimes above ZOMG

The following are some additional comparisons on the interactions between towers and Dark Dirigible Titans, besides simple targeting of ZOMGs over DDTs:


 * Pirate Lord will target ZOMGs first before targeting any other bloon type, starting with Fortified DDTs and then DDTs, then BFBs and M.O.A.B.s.
 * Bomb Blitz's description claims that it can fully destroy DDTs, BFBs, and M.O.A.B.s, but not ZOMGs.
 * Super Glue can fully stun DDTs and Fortified DDTs but not BFBs or ZOMGs, making DDTs seem as weak as M.O.A.B.s in this interaction.
 * Unstable Concoction requires additional pierce for DDTs to be coated in explosive chemicals when compared to M.O.A.B.s. The requirements for DDTs are just as much as is required for BFBs, making DDTs seem as strong as BFBs.
 * MOAB Press special knockback boomerangs will only slow DDTs instead of pushing them backward, and even then the knockback boomerangs will not always hit DDTs due to the fast speed of such bloons.
 * MOAB Domination stuns any affected MOAB-class bloon before pushing them back a fair distance. Unlike MOAB Press, MOAB Domination affects DDTs similarly to when against MOABs.
 * MOAB Shove will slow down DDTs (with camo detection) but not push back like M.O.A.B.s or fully stall like BFBs, making DDTs "stronger" than BFBs and M.O.A.B.s, and just as strong as ZOMGs.
 * MOAB Assassin and MOAB Eliminator abilities cannot target DDTs without camo detection, but if given camo detection they will still target ZOMGs over DDTs. Similar interactions occur for Bloon Master Alchemist's passive bloon-transformation ability.
 * Maim MOAB and Cripple MOAB will stun DDTs for 1.5 seconds and 4.0 seconds, respectively. Cripple MOAB stuns last longer compared to ZOMGs, at 3.0 seconds instead.
 * Shattering Shells can remove the fortified property from M.O.A.B.s and BFBs but not from DDTs, ZOMGs, or BADs, making DDTs appear as strong as ZOMGs in the case of interacting with Shattering Shells.
 * Blooncineration can decamo and defortify DDTs without support, but it cannot defortify ZOMGs at all, making DDTs appear weaker than ZOMGs when interacting with Blooncineration.
 * Sun Temple max magic sacrifices can blow back M.O.A.B.s but not BFBs, DDTs, ZOMGs, or BADs.
 * Benjamin's Syphon Funding ability cannot affect DDTs regardless of upgrades, while his Bloon Trojan attacks cannot affect DDTs or BFBs until Level 18. On the opposite side, ZOMGs cannot be at all targeted by Bloon Trojan, but it will always be affected by Syphon Funding regardless of level.
 * Snowstorm, Absolute Zero, or Icicle Impale frozen statuses onto DDTs slow them to a set slower speed, while frozen ZOMGs become only 50% slower.

In addition to these anomaly interactions with DDTs, DDTs possess additional strengths that may be considered weaker or stronger than ZOMGs. DDTs also contain only 4 ceramic bloons in BTD6, while the number of bloons from a ZOMG can easily overwhelm defenses even if all the MOAB-class layers are popped. Sometimes, a DDT may not be much of a problem until later freeplay rounds, where their speed and health increase due to ramping. As the round number increases, beyond 500, DDTs could outrun other bloons before other towers could attack it in time.

Quotes
"This fast and terrible bloon combines all abilities of every other bloon. You'll have to best them sooner or later. They are noticed by their black coloring."

- "Dark Dirigible Titan" Quest description in BMC

"Our scouts came running back to base looking as if they'd seen a ghost. Apparently they spotted a bloon like nothing they've ever seen, a DDT combining the properties of all other bloons. Let's prove that nothing will stand in our way!"

- "Dark Dirigible Titan" quest start description in BMCM

"DDTs are large, black MOAB Bloons that have the same properties as camo, lead and black Bloons."

Trivia

 * Ironically, the DDT is the second smallest MOAB-Class Bloon in the game.
 * The various damage stages and the hull color suggests that DDTs are made from a hard, rigid, metallic material (potentially iron due to the color ) instead of fabric like all other M.O.A.B-Class Bloons
 * DDTs are the fastest MOAB-Class Bloon in the Bloons Tower Defense series.
 * DDTs, similar to ZOMGs, are diamond-shaped and pointed rather than rounded like M.O.A.B.s and BFBs, as well as BADs.
 * It is one of the five Bloons in the series to release more than four children (the others are the Bloom Bloon in Bloons 2, the BAD in Bloons TD 6, and MOABs and BFBs in Bloons Super Monkey).
 * However, the DDT only releases four Camo Regrowth Ceramic Bloons in Bloons TD 6.
 * Despite having all bloon properties, the DDT doesn't have the health of a BFB, a ZOMG and a BAD, and its health is instead in between a M.O.A.B. and a BFB
 * This is probably because the DDT would be too difficult to pop if it had the health of a BFB/ZOMG/BAD
 * Although Ground Zero takes 1 hit to destroy a DDT, but won't pop the children, MOAB Assassin and MOAB Takedown can completely pop the DDT layer.
 * However, DDTs come often on groups, and Assassin/Takedown abilities can only destroy 1 DDT per ability, it's better to use Ground Zero, as infinite DDTs can be popped, and it's likely for players to have towers that can defend against the Regen Camo Ceramics, though one can argue that selling and rebuying is a better choice.
 * DDTs can lose their Camo Property from Cleansing Foam, Anti-Camo Dust and Submerge and Support. In BMC and BTD6 before update 2.0, it still appears to have the camo status on the blimp.
 * To be prepared, the player is most likely to encounter M.O.A.B.s and BFBs. If the player has reached far enough, the player will encounter ZOMGs, with DDTs as well.
 * It is one of the three MOAB-Class Bloons with special abilities (the other two being the ZOMG and BAD which are immune to Monkey Pirates).
 * In Bloons TD 6, prior to version 8.0, the DDT lacks propellers. Yet, it does have propellers in Bloons Monkey City, and Bloons Adventure Time TD, It regained it's propellers in 8.0 and Beyond.
 * The DDT looks very similar to the Lockheed F-117 Nighthawk.
 * The name of a DDT could be a reference to real life DDT, an extremely powerful pesticide which has been banned worldwide.

Specific to Bloons Monkey City

 * DDTs can come on Round 19 in Bloons Monkey City. ($1080+/$1188+ in Grassy Pass and $1000+/$1100+ in Bloon Dunes.)
 * Technically, the outer layer is harder to beat than a ZOMG's, because although the ZOMG has 4000 health compared to the DDT's 300 (Blimp health is reduced in Bloons Monkey City), the DDT has the abilities of a Black, Lead Bloon and Camo Bloon and moves nearly 20 times faster than the ZOMG, or as fast as a Pink Bloon, making it an extremely fast bloon.
 * This makes DDT tiles a bit harder than ZOMG ones, as they come in groups of three and spaced. However, this might suit M.O.A.B. Maulers.
 * A single ZOMG can be beaten in BMC with 6 MOAB Maulers under a 2/3 Village and a 3/2 Ice Tower, but 3 DDTs require more (around 12, or 6 with Monkey Boost).
 * DDTs come in groups of 3, 6, 9, etc. on the flash version of Bloons Monkey City.
 * In Monkey v Monkey attacks, groups of only 1 or 2 DDTs can appear.
 * On the Mobile version, they usually come on their own, in couples, or very rarely grouped in 3.
 * They do not appear in Contested Territory on Bloons Monkey City Mobile. They are replaced with mainly more ZOMGs.
 * DDTs do not appear in M.O.A.B. Graveyard despite the fact that they are a M.O.A.B. Class Bloon.
 * This is most likely because they would come very quickly and rush through the short map, leaving little time to deal with them.
 * DDTs can be sent in Monkey v Monkey prior to the October 10, 2014 update. Moreover, the Armored Stealth Silo is required to send DDTs to another player.
 * In Mobile, such a building is not available; although DDTs can spawn in ZOMG attacks if the Bloon strategy is either Camo Craziness or Fast and Furious.
 * If a Bomb Shooter or Mortar Monkey is in the range of an x/2 Monkey Village (or if the mortar has signal flare) hits a DDT, it will make the same noise that Lead Bloons make when a tower can't pop them despite it not being the reason it can't damage it. This does not apply to the towers' respective left-sided 4th tier upgrades.
 * No tower in BMC Flash and BTD6 can damage DDTs without upgrades unless they are under the effect of an upgraded Monkey Village. The same thing applies to Road Spikes (BMC only) and Pineapples.
 * However, since the DDT lacks Lead and Black properties in BMC Mobile, only the Ninja Monkey, Dartling Gun, and Spike Factory can damage it without upgrades and further support.
 * Curiously, the DDT's final health stage in BMC Mobile depicts the metal that encircles the middle of the blimp no longer cracked, as the 3rd health stage had shown. The rip near the bottom is also fixed. It's as if the DDT has regenerated itself (for aesthetic purposes only), foreshadowing its children's regenerative status.
 * In Contested Territory on the flash version of BMC, DDTs become very dangerous after round 30 from HP and speed ramping. Without proper countermeasures, a DDT on Round 100 will charge through most tracks in just 3 seconds on average.
 * In Bloons Monkey City Mobile, DDTs can appear on ZOMG tiles. They are most common on the strategies Camo Craziness and Fast & Furious. Outside of these strategies are much rarer to appear.
 * DDTs can sometimes "jump" over placed spikes, evading the damage and charging through the spikes of a spike factory. Despite this, having multiple spiked mine upgraded spike factories at the end of the track is a good way to get rid of DDTs in contested territory on flash, as these can be enough to eat a DDT even if the round only just started, and it does not require village support due to the white hot spikes upgrade, and naturally popping camos.
 * In BMC Mobile, the Monkey Sub's First Strike Capability missile targets DDTs over ZOMGs.

Specific to Bloons TD 6

 * Despite that the Pre-Round Comment on Round 90 says that the DDT has the properties of a Pink Bloon, the DDT is actually slower than the Pink Bloon; in reality, it's slightly faster than a Ceramic Bloon but slower than a Purple Bloon.
 * This could be because the ramping past round 80 increases the DDT's speed to that of a pre-round 81 Pink Bloon by round 90.
 * The DDT does not gain the properties of the new Purple Bloon, meaning DDTs no longer have all the properties of non-M.O.A.B. class bloons. Moreover, most blimps can be frozen in BTD6, meaning the DDT lacks White/Zebra properties.
 * The DDT can easily be dealt with through the use of the Monkey Sub's tier 5 ability, Pre-Emptive Strike as it launches a M.O.A.B. Assassin-like missile towards it upon spawning, destroying the blimp layer instantly.
 * This does not work with Fortified DDTs, as they have 800 health, allowing them to withstand the 750 damage from the Pre-Emptive Strike missiles but bringing them to critical health.
 * It received a slight nerf, its speed is now 75% of the Pink Bloon, it releases 4 Camo-Regrow Ceramics when destroyed instead of 6 but now has 480 base health instead of 300.
 * The DDT in BTD6 has a Camo pattern which is nearly invisible, while in Bloons Adventure Time TD it doesn't appear to have any camo patterns on it visually. In both cases, it still does have the camo properties.
 * Compared to the M.O.A.B., it has 2x the amount of health (4x stronger if a fortified DDT was compared to a Regular MOAB).
 * For all preset rounds, DDTs will always come in threes, similarly to BMC. Round 90 has 3, 93 has 6, 95 has 30, 99 has 9 fortified, and the BAD contains three DDTs as well.
 * Round 10005 is preset to have 100 non-fortified DDTs, breaking the pattern, although Rounds that high are normally impossible to reach due to ramping.
 * This pattern is also broken in the Alternate Bloons Rounds gamemode, as DDTs can appear in fours or sevens.

Specific to Bloons Adventure Time TD

 * Prior to version 1.3, there was a bug that allowed the DDT's children to regrow back into DDTs, making them very difficult to beat if it did happen, allowing tens, hundreds, or even thousands of DDTs to overwhelm the player's defenses.
