Boomerang Monkey (BTD7)

The Boomerang Monkey throws a boomerang in a unique circular route. Each Boomerang has a pierce of three Bloons and takes off one layer on each Bloon it hits. The ability multiplies the Boomerang Monkey's attack speed by 4x for 10 seconds. Tier 5 and 6 enhance this ability. Tier 5 multiplies the attack speed by 6x instead of 4x and Tier 6 makes the boost permanent and makes the ability double that attack speed. Other Tier 6 abilities can either send out four permanent glaives to rotate around the Boomerang Monkey or throw kylie boomerangs that deal lots of extra damage to MOAB-Class Bloons. No upgrades except for Glaive Lord grant Camo detection and Red Hot Rangs grants the ability to pop Leads.
