Packed MOAB-class

Packed MOAB-class is a term given to a group of densely packed MOAB-class. Unlike Bloon Rushes, which only refer to non-MOAB-class bloons, Packed MOAB-class does not give money to hits of the MOAB-class group, and require more hits to destroy such blimps. Such rushes can appear very late in the game, and are capable of spawning mass Bloon Rushes after the destruction of the blimp layers.

Appearances
Packed MOAB-class can appear in the very late rounds, especially if over Round 90 in BTD5. They appear much more often on tiles with Packed MOAB or Packed BFB tiles. Packed MOAB-class can also be made by the spawned children of a ZOMG, BFB or BAD.

Packed MOAB-class may appear in some Random Challenges where bloon ranks are raised, such that Ceramics turn into MOABs. They will also appear in Mastery Mode, such as in Round 63, Round 76 and Round 78, where there are 122 MOABs in Round 63, 60 MOABs in Round 76 and 147 MOABs in Round 78.

Strategies
Usually, spamming in many strong towers will counter Packed MOAB-class, but can be difficult due to costs.

Trivia

 * "Packed MOAB" and "Packed BFB" are both confirmed terms from Bloons Monkey City, but "Packed MOAB-class" is just a term coined by fans.
