Underfist: The Final Showdown

Underfist: The Final Showdown is a spin-off special of Gummy Bear, Crazy Frog, Masha and the Bear, Susie the Little Blue Coupe and Dinotopia. It aired on July 20, 2010. The special was going to be a setup for a new series, but Michael Redd’ contract with Cartoon Network had expired before the series could be greenlit, so the special was the end of the franchise. BOSS HOSS!
