The Bloon Ball

The Bloon Ball is a special mission in which you must defeat 40 waves of bloons while both the bloons and the towers move in patterns as though they are doing a waltz. Towers must also be placed in pairs, near enough to each other that they can do the correct waltz movements together. Bloons will come in pairs as well, but will do the movements while moving in the general path direction. The track this takes place in looks like a ballroom, and when you complete the mission, you will get $220 Monkey Money.
