Teenage Mutant Ninja Turtles: Turtles Forever

After a news story which reports that large green creatures have been spotted on security cameras during a robbery, the turtles analyse a screenshot and find which criminal organisation was responsible and go to their headquarters to investigate. Once there they discover another four mutant turtles that share some similarities but are more goofy, comical, and completely obsessed with pizza. Their Leonardo deduces that his group were transported to a different dimension - with its own version of the turtles - after an attack on the Technodrome over some mutagen went awry. Meanwhile, inside the Technodrome, Shredder and Krang contemplate the same scenario and decide to find and ally with this dimension’s version of them, bringing back the Utrom Shredder Ch’rell.
