Mellow Kitty

Mellow Kitties are a species of cats seen in Wario: Master of Disguise. They are found in Carpaccio's Lab during Wario's adventure there. They appear to be cat-like bubbles with a teal design surrounding them. They attack by consuming Wario. Any non-physical attack kills them, and being tapped by the stylus several times after eating Wario works too.

Trivia

 * The name Mellow Kitty is a pun on Hello Kitty.
