Primary   Yo-yo The standard weapon Mikey begins. Slingshot Maximum 40 bullets. The slingshot is good for long-range attacks. Boomerang Another long-range attack weapon, the boomerang is food for the floating head enemies Mikey meets while crossing the bridge. Harpoon Replaces Mikey's yo-yo during underwater stages. Secondary   Bomb Can be used to uncover hidden doors and blowing up enemies. Molotov Cocktails Much like napalm, throwing one will cause a wall of flames to kill any enemy close enough to impact.
