King Watinga
Watinga is a large robotic insect which appears as a boss in the Gnat Attack mini-game of Mario Paint. Watinga is capable of shooting out stinger missiles and poison gas, he is also capable of flight. After being hit multiple times, Watinga will begin going into convulsions and subsequently explode.
Watinga's only other game appearance was in a remake called Fly Swatter, which was one of 9-Volt retro games in WarioWare, Inc.: Mega Microgame$.
Watinga also made a small appearance in Volume five of the Super Mario-Kun Japanese manga, in which he was brought out of the Mario Paint game by Lemmy Koopa. After colliding with Yoshi, Watinga was fused with him. In the end he was destroyed, and Mario was able to redraw Yoshi. He wasn't given a name in this comic and was simply called "Fly Assault Game's Boss".
