Fly Bomb

Bomb Flies are Bob-omb-like insect enemies in the game Gnat Attack, a minigame in Mario Paint. If a Bomb Fly is swatted or left alone, it explodes, so Mario should try to avoid them. They are some of the last enemies encountered before Watinga, the final boss of the game. They reappear in Super Mario Maker as part of the Gnat Attack minigame and one second from the timer is deducted if a Bomb Fly explodes.
