This is some artwork from season 7 (1993). These episodes were made after I’d left the show, working on Exosquad, among other things.
The TMN Turtles are on a mission to save the Planet of Turtleoids – Shellri-La. A two-foot dwarf turtle, Kerma from the Shellri-La is asking for help to save his planet from the two-headed dragon – Herman the Horrible. The arch rival Shredded is all set to destroy the peace of town in the mean while with a gigantic robot and two new mutants. Can the TMNT save the Shellri-la from Herman the Horrible? Can they defend Shredder from his evil dreams? Watch out for more with our original Ninja Turtle cartoon artwork!
