The WarioWare series (called Made in Wario in Japan) is a series of games starring Wario, the anti-hero from the Mario spin-off games. The premise of the series is that Wario, in his quest for infinite riches, creates his own video game company, WarioWare Inc., where he hires his friends (unpaid, of course) to create "microgames" to sell for high prices.
WarioWare: Twisted! was released for the Game Boy Advance in 2004. The game's cartridge contains a tilt sensor, which is used for the game's main gimmick: twisting.
Pyoro R is an unlockable souvenir in the game. The player must tilt the Game Boy Advance to aim, and press the A button to extend Pyoro's beak and attack any invading bugs. The game is over if a single bug reaches the ground. For the larger enemies, the player must rotate the Game Boy Advance after attaching Pyoro's beak, which cause Pyoro to slightly inflate.
