Ninja Turtles: The Next Mutation

Trusting Dr. Quease (1x22)

:

(Synopsis credited to Ninja Turtles.com) When Dragon Lord and Dr. Quease have an argument, Quease contacts Donatello because, in his mind, they are the two most brilliant creators on the planet and he thinks they should work together. Don is naturally suspicious, but can't resist the opportunity to collaborate with the great, though deranged, scientist.
