I.G.B.M.

The I.G.B.M ( I ntelligent G  igantic  B loon  M issile) is another idea of an Easy Mode boss. Its speed is somewhere between a Yellow Bloon and a Pink Bloon. It takes 1000 hits to pop and doesn't spawn any children. In Normal and Hard Mode, it can choose to hits one of your towers, destroying towers in a HUGE radius (this is the only attack that's truly undefendable and can destroy a Temple of the Monkey God in 1 hit!). Don't worry, it won't always do this and it'll never do this in Easy Mode (because it means it's an instant win for the monkeys)

Trivia
