Tiny Toon Adventures 3 is a pirate game for the Sega Mega Drive. Despite the name though, the game has nothing to do with Tiny Toon Adventures besides the main character being a rabbit having a small resemblance to Buster Bunny.
Although the developer is not credited, the art style bares a similarity to Adventurous Boy, and like The Lion King II and Squirrel King, is based off a cartoon franchise, leading it likely to be developed by Gamtec.
