Teenage Mutant Ninja Turtles

Four turtles fall into the sewers and are taken in by Hamato Yoshi, a Japanese man who moved to New York but ended up living underground. One day, a mysterious green glow transforms the turtles into humanoid creatures. The same glow turns Hamato-now called Master Splinter-into a giant rat. He trains the turtles in ninjutsu, and they eventually join forces with reporter April O'Neil to fight Yoshi’s old rival, the Shredder, and Krang, an alien warlord from Dimension X.
