Ooze is one of the most important recurring themes in the Teenage Mutant Ninja Turtles, from the creation of the Turtles to the mutation of friends and foes in each episode. 2.4-ounces of the fun and mysterious Mutagen Ooze are sold in each cannister (non-toxic and stain resistant). Ooze is fun to play with by itself and also with specially-marked Turtle figures, vehicles, and playsets. Bonus Mini Turtle inside, collect all four!
