Mazes & Mutants -The copy the Turtles' have was first owned by a kid named Martin Miltin. But when Martin was feeding the sparrows on the rooftop, a Mutagen Ooze canister fell from the sky and hit him right in the head knocking him unconscious, along with the birds he was feeding. He then turned into a sparrow mutant named Sir Malachi. When he was playing the game down in the sewers, he saw the Turtles pass by him. He hid the game hoping the Turtles will find it, and when they found it they loved it so much. It made Malachi so happy.
- The game itself is a reference to the old 80's board game "Dungeons and Dragons", a game featuring monsters, trolls, and demons as enemies, with a tape of an animated version of the story to go with it.
