Mace Bloon

This Green Bloon bears a heavy mace that it smashes towers with. Because the mace is tied around itself, it moves slower than other bloons, but it swings that thing around and does 3HP damage when it hits a tower (5HP if a Sword Monkey or Pike Monkey took a hit). It takes ten hits to remove the mace.

In the Bloonopedia:
Weight: 13 Speed: Very Slow

This is what happens when you tie a mace around a Green Bloon. This monstrosity is super-hard to kill, but still can be glued and frozen. Explosives have a damage bonus on this beast, but still contains a wimpy Green Bloon...
