Hippopo

Hippopos are enemies in Super Mario RPG: Legend of the Seven Stars that look like big blue hippopotamuses with large ears (also somewhat resembling beetle wings) and a small blue warrior mounted on them. They appear in Smithy's Factory. Hippopos can accompany Glum Reapers, Ameboids, Li'l Boos, and Ninjas in battle, appearing in all parts of the factory before the final hall to Smithy. They can also fly, making them capable of using aerial attacks. Hippopos are also able to using various magic attacks, such as Drain Beam, Solidify or Sand Storm.

Among the unused enemies of Super Mario RPG: Legend of the Seven Stars, there is one named Crippo, which is a Hippopo lookalike. It has twice as much health as Hippopo. The only noticeable difference is Crippo's brown and green color and the moves Thornet which could lead the monster to attack itself and Doom Reverb. It is also possible that Crippo's name is a portmanteau of "cripple," referring to them attacking themselves, and "hippo." The unused enemy has no Psychopath thought.
