The MOAB (known as the Mini MOAB prior to version 0.8) is a type of Boss Bloon in Bloons Blitz. It attacks by charging towards the player and spawning bloons around it.
The MOAB behaves similarly to the Wild Zebra, having 2 attacks:
Moves within striking distance, then aims towards the player, charging up a dash. Once it is done charging up, it dashes after a short delay. It uses this attack one extra time in a row for the first two skulls lost, and sometimes dashes a 4th time if 3 skulls are lost. Unlike the Wild Zebra, it does not charge up again on subsequent dashes.
Faces upwards and spins, rapidly spawning bloons and energy bloons in all directions. After a bit, the attack stops spawning energy bloons.
