C.R.S.G.B.

The Camo Regrowth Shielded Green Blimp is, well, a camo regrowth shielded green blimp. (Actually a semi-blimp) It has 1000 health and a shield with 100 health. The shield regenerates 5 seconds after destroying it, and attacks can't pass through it. (That means all towers, including snipers, have to break the shield before hitting the C.R.S.G.B.!) It holds 5 Camo Regrowth Green Megabloons. The Megabloons will not grow back into more C.R.S.G.B.s. It has 0.3x the speed of a Green Bloon and first appears on round 80, though it also appears in freeplay. Sounds underpowered? Here are the abilities:

Green Pulse: Sprays 50 Green Bloons, 40 Camo Green Bloons, and 10 Green Megabloons in a Spike Storm manner, though they won't spawn within a 50px radius around the exit. Used every 5-10 seconds.

Green Sacrifice: Sacrifices all its HP to make ALL Green Bloons on the screen turn into Camo Regrowth Rainbow Bloons! Has a 10% chance to be used 3 seconds after Green Pulse. (See above)

Bloons Super Monkey 3 Form
In Bloons Super Monkey 3, it appears as the boss of Green Land. It now takes 5000 hits, and a shield that takes 1000 hits and regens 20 seconds after being destroyed. Every hit, it launches a Green Bloon until 4000 hits, where it then spews out Regrowth Greens, then Shield Greens at 3000 hits, then Camo Greens at 2000 hits, then Rainbows at 1000 hits, before finally exploding into 8000 Green Bloons and 1001 Rainbow Bloons.
