Inamazu

Inamazu (イナマズ ) are enemies in Wario Land II. They are catfish walking on land that can charge up electricity using plugs on their heads. They send the electricity rolling along the ground at Wario. Their name is a pun on inazuma (稲妻, lightning) and namazu (ナマズ catfish). Given that they wear bandanas, they seem to be members of the Black Sugar Gang.
