Gnat Attack

Gnat Attack (also called Coffee Break) is a minigame found in Mario Paint, in which the player must use the SNES Mouse to swat different fly-like enemies. The player controls a gloved hand (similar to the one seen on the title screen) holding a flyswatter, which must swat flying insects on the screen, before the insect stings the player's hand in one way or another. There are three levels, each with 100 insects; after defeating them, the boss, Watinga, appears. Completing stages causes Mario characters to walk across the screen. When the player wins the last boss it takes them back to level one and adds a small icon in the top left corner of the screen; there is no final level or reward, as the game will loop endlessly, getting slightly harder each time.

Gnat Attack was modified into both a microgame and a bonus minigame in WarioWare, Inc.: Minigame Mania, under the names Mario Paint: Fly Swatter and plain Fly Swatter, respectively. The microgame involved shooting the flies as they flew past a fixed target, while the minigame was more faithful to Gnat Attack's gameplay.
