I unlocked the most awesome minigame in Wario Ware Twisted. It's called "Mewtroid" and you play as this adorable little kitten with a gun. When you tilt the Game Boy, the kitten rolls over and pulls out its gun, and you shoot these really poorly drawn bugs (low point of the game). And the background music is the Zebes theme from Metroid!

Yes, I know it's not much of a game, but it's a kitten with a gun!

What's odd is "Mewtroid" was some halfassed idea for a Pokemon I created as a kid. It was a green Mew that could suck the life out of things.
