4 baby tur-tles
1 jar of ooze
1 New York sewer
1 former pet rat of a Japanese owner that did karate
4 sets of quality weapons just lying around
4 Renaissance artists
1 Shredder (not for cheese)
Age the 4 baby tur-tles to teenhood. Sprinkle them with martial arts training. Feed them pizza and skateboards periodically. Sometimes they fight crime. Add 1980's and 1990's merchandising.
Set to COOL.
Congratulations, you've made Turtle Power!
