Rammerhead

Rammerheads are enemies from Super Mario 3D World. They are semi-rare enemies and their name is a portmanteau of "hammerhead" and "rammer". They only appear in the levels Rammerhead Reef, Captain Toad Makes a Splash, and Pipeline Boom Lagoon.

Rammerheads are pink (purple underwater) hammerhead shark-like fish with wide, spiked, roll-shaped snouts. They come in two sizes: the big ones are common, while small ones are rare. These enemies have three types of attacks: some swim in a predetermined pattern, some swim around stones, and others jump out of the water. Only the spiked portion of their heads cause damage; their bodies themselves are harmless. They can only be defeated by Invincibility and by Ground Pounding on them in the Lucky Cat form.
