B.A.K.A.

The B.A.K.A., short for Blimp of Aerating Kooky contrAptions, is a M.O.A.B.-Class Bloon that contains 9 Zebra Bloons. It looks similar to a B.F.B., except smaller, light blue, and has a circled 9 on it instead of an anti-monkey symbol. Also, it has 6 blue crystals floating on its sides. The crystals appear to flap as it moves. It has 999 HP.

Abilities

 * Perfect Freeze: Stops moving and freezes all towers within a short radius of the blimp's centre. Frozen towers are effectively disabled for about five seconds, or until hit with an X-2 Mortar Monkey shot.
 * Icicle Fall: Moves to the top of the screen (in a 2-D sense, lol) and spams icicles down. These never hit anything. After about thirty seconds, it moves back to the track.
 * The Strongest: Any bloon on the screen other than a Zebra Bloon or a B.A.K.A. is popped by all layers, and, for every bloon popped, it adds 81 HP (9 squared HP) to the B.A.K.A.

Trivia

 * This was SUPPOSED to be added on Cirno Day (September 9th), but I got sidetracked.
 * Pretty much everything about this bloon is a reference to Cirno.
 * Why does this bloon contain Zebras? Because they are spawned with the 9 button in Sandbox Mode!
