Teenage Mutant Ninja Turtles began as a comic, but later spawned a long-running cartoon series, many video games and toys. It tells the story of four teenage mutant turtles, named after Italian painters and trained by a mutant rat called Splinter. They eat pizza and live in the sewers of New York City, where Splinter teaches them ninjutsu. They fight the evil Shredder, a samurai in metal with a mutant rhino and boar as his subordinates, as well as Krang, a creature which looks like a brain with a mouth, eyes and arms.
