Mewtroid

Mewtroid is an unlockable minigame in WarioWare: Twisted! that appears to be a mixture of the two Metroid microgames in Twisted!, Metroid-Morph Ball and Metroid-Samus. Mewtroid features a cat with a "paw cannon" blasting insects while rolling around on the floor with the Metroid Brinstar theme playing. Tilting the game will cause the cat to roll, but if the cat is left still for a few moments, then it will automatically turn and lay on its belly and then meow, mostly concealing the paw cannon and appearing like a normal cat. A quick tilt will cause the cat to roll very fast and play a Spin Jump sound effect. The "A" button fires grey steaking beams.

Several varieties of "evil bug" enemies appear in this game, but all have a human face and moustache. The first are Reo-like, with wings and dangling legs. These enemies move across the screen before lowering slightly and moving to the other side, like Space Invaders. The second type of enemy has the same face but moves like a Sidehopper and also switches direction if it reaches the opposite side of the screen. The third to appear is a "boss" enemy that has a goatee, sunglasses, two horns, and wings. This slightly resembles a Metroid, upside down. The boss will bounce around the stage and fire one round shot at a time and require 15 shots to kill, blinking a darker color when hit and making a faint rooster call when killed. The fourth enemy to appear, after the boss, is a darker variation of the jumping bug, which turns white when shot once and requires a second shot to defeat. If shot fast enough, it will still be dark when it falls offscreen.
