Sharkbone

The Sharkbone appeared in 2003 video game called Mario & Luigi: Superstar Saga. The Sharkbone is an enemy that appears in Mario & Luigi: Superstar Saga and its 3DS remake, Mario & Luigi: Superstar Saga + Bowser's Minions, where it is found in Gwarhar Lagoon. The name of the enemy was originally based on unused enemy name text, and it also appeared as the undead shark's name in the Nintendo Power guide. The easy mode hints in Mario & Luigi: Superstar Saga + Bowser's Minions officially refers to them as "Sharkbones".

Sharkbones are skeletal shark-like creatures that always appear in groups with the dorsal fin-wearing Sand Cheeps; both remain submerged up to their dorsal fin in the sands in order to disguise themselves. Both enemies are also often fought with Beanerang Bros..
