Teenage Mutant Ninja Turtles: Teenage Mutant Ninja Turtles The Incredible Shrinking Turtles: The Turtles go along with Michaelangelo and his pet pigeon Pete to the zoo so that Dr. Goodfellow can check the bird out. After the examination, Michaelangelo sets off on his own while the other Turtles head home. Just as they are about to leave, Donatello, Leonardo and Raphael get nabbed by robots created by Dr. Lesseau. The robots take the TMNT to an island near the zoo where Dr. Lesseau is awaiting their arrival. Dr. Lesseau is a scientist who is using his robots to steal animals from the zoo. He is experimenting on them to create a single animal with the best traits of all animals combined. The mad Doc wants the Turtles for their brains. Michaelangelo returns to the lair and finds the others missing. Splinter tells him that he had had a vision of an island while meditating and believes the other Turtles are in danger. Splinter sends MIchaelangelo to search for them even after he tells his master he has no idea where to start looking for them. When Michaelangelo arrives at the place where the Turtles were taken, he finds Pete waiting for him. Pete tells him what happened to the other Turtles. Just then Dr. Jane Goodfellow shows up. She is trying to find out who is taking the animals from the zoo. Michaelangelo tells her about the disappearance of the other Turtles and the three of them set off to find the Turtles and the missing animals from the zoo. Using the zoo's boat, they row out to an island that they think the Turtles are on. Dodging all of Dr. Lesseau's booby traps, Michaelanglo, Pete and Dr. Goodfellow arrive at the island unharmed. They reach the doctor's lab before he has a chance to follow through with his experiment on the other Turtles. Dr. Lesseau sets his animals free and orders them to attack the Turtles, but the animals turn on the doctor and capture him. Donatello uses Dr. Lesseau's mutator laser to turn all the animals back to normal and return them to the zoo.
