Mewtroid

Mewtroid is a minigame souvenir found in the Games folder in WarioWare: Twisted! Its name is a combination of "mew," the sound cats make, and Metroid. The player controls a cat, and must shoot down as many bugs as possible. When rolled over, the cat can shoot from its arm cannon. Each time thirty bugs are defeated, a powerful bug that takes multiple hits to shoot down will appear. If the cat touches a bug, the game will end.
