R.R.A.B.

The RRAB Recursive Acronym Blimp is an MOAB-class bloon.

It has 300 health.

When popped, it spawns a random bloon up to and including rainbows, and has a 90% chance of spawning another RRAB with 1 less HP and a 30% chance of spawning another RRAB with only half as much health, rounded up if nescessary. However, if it spawns with 0 HP, it is immediatly destroyed releasing only a camo regen ceramic (this can not regenerate beyond ceramic level.)

It is immune to all towers with acronyms in their current names.
