These enemies are rather bog standard. They charge at characters and attack with semi long ranged needle attacks. They're probably the most threatening enemy in this stage, if only for their damage output, which can be three times higher than the Green Box Tree and the Blue Box Copter. Weapons of the type Freeze, especially Freeze Explosion 6, work very well, especially when they appear in large mobs. They also drop an astonishing 3333 Gold, so they're great for grinding money.
