Episode Title:
Donnie Goes Deep
Episode Description:
Donatello and Wingnut are on their way to fix the sewer lair's power supply when Lee the Eel dashes through the sewer tunnel, forming a hole that plunges them into the lower levels. They notice rising water and an alligator, which they assume to be a de-mutated Leatherhead. After clashes with the alligator, Donatello tries to connect with it, still thinking it's Leatherhead. The real Leatherhead then arrives, revealing the alligator they are fighting is different. Donatello, Wingnut, and Leatherhead together take care of the alligator and an additional one. The trio head for the exit and run into Raphael, Scumbug, and Ray Fillet. In a flashback side story, the East River Three devise a plan to retrieve the giant pearl that was taken by humans from their East River home. Goldfin decides to ask crime boss Bad Bernie for help.
