MOAB Takedown ability: Grapples a MOAB-Class Bloon and brings it down.
~ BTD6 description
Monkey Pirates is the final upgrade of the path 2 for the Monkey Buccaneer in Bloons Tower Defense 5. It costs $3825 on Easy, $4500 on Medium, $4860 on Hard and $5400 on Impoppable. Along with Aircraft Carrier, this upgrade is unlocked at Rank 29 in Bloons TD 5. It adds the MOAB Takedown Ability, which targets the strongest (the closest if there are more bloons of the same strength) bloon on screen (excluding ZOMGs) and brings it down with a grappling hook. You get $300 for destroying a MOAB, $800 for destroying a BFB and $1 for other bloons. Cooldown is 60 seconds.
In Bloons Tower Defense 6, Monkey Pirates returns as the fourth upgrade of Path 2. Along with its Monkey Pirates ability, all of its Cannon Ship bombs deal +1 damage. The ability can only be used for MOAB-class bloons, and the amount gained depends on what round you are on as well as the blimp pulled (still $300 per MOAB, $800 per BFB, $300 per DDT, ignoring cash-gain decreases), refer to the money table. Note that the Alchemist's Rubber to Gold does work on MOAB-classes, allowing you to get 3x as much cash if they are affected. There is a cooldown of 50 seconds before using the ability again.
Monkey Pirates is helpful at grappling down nasty BFBs and DDTs that can sneak by.
Monkey Pirates does not require Crow's Nest to pull down DDTs, as the ability can pull any blimp (except ZOMGs and BADs) regardless of camo detection or not.
Version History (BTD6)
Monkey Pirates cooldown reduced from 60 to 50
Bomb attack damage increased from 1 to 2
2 Monkey Pirates catching 2 completely different Bloons. The weakest and the strongest.
Even though the in-game description says that it takes down the nearest MOAB-class bloon, it can also take down anything from red bloons up to D.D.T.s except for Z.O.M.G.
In Bloons Monkey City, this upgrade requires building a Pirate School first, then buying the upgrade.
When it is hooking a bloon midway, it cannot use regular attacks on other bloons.
If a bloon (or MOAB-class bloon) is very close to or on top of the Monkey Pirates and you use the ability, the bloon will be caught but the hook will go outwards instead of inwards.
The name is "Monkey Pirates" (plural) but the in-game Buccaneer and the artwork only shows one Pirate Monkey on the ship.
Monkey Pirates' MOAB Takedown Ability can actually add to the damage count, unlike BTD5.
In BTD5, the description says that it takes down MOAB-Class Bloons, but can hook normal Bloons instead if no MOAB-Class Bloons are present. While in BTD6, it can only hook MOAB-Class Bloons, similiar to the discription.
