Ninja Turtles don't just fall out of the sky. They have to be created with a complex mutagen formula. Also, we think pizza fits into the equation somewhere. If you're girl wants to skip that whole mutation process, then it might be a bit safer to turn her in one of the Teenage Mutant Ninja Turtles by some other process, like this cute dress, licensed from the movie. It has Donatello's signature purple colors and a cute tutu style skirt. No mutagen required!
