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.

While inside a Mellow Kitty, Wario will lose experience points for his currently-selected disguise, but he will not lose any HP. He will not, however, drop a level. Therefore, once Wario has levelled all his disguises up to Level 3, this enemy is harmless.

In-game Description
''This cat burglar has no interest in the true value of his loot. He just likes to stare at shiny things.''
