Operation

 is the 8th level in the Frosty Fun area in Bloons 2. It is relatively easy in difficulty as all it really requires the player to do is hit the Spikey Bloons in the correct order.

Strategies
Firstly, pop the Bonus Dart Bloon and normal Bloon first, then hit the Ice Bloon and Bomb Bloon (Do all of this by hitting the Spikey Bloons around the top so that the spike balls hit the bloons, not the darts)

Trivia
