Fan CastingThe TMNT S1 Ep4 Give a Dog a Bone

While testing the mutagen Baxter Stockman and Shredder end up turning a man named Chris Bradford into a giant dog monster. Meanwhile the turtles and Casey Jones are still investigating the ooze until they're attacked by the dog monster who Michaelangelo names Dogpound. The turtles are beaten by Dogpound and Dogpound goes back to rampaging through the city. The turtles and Casey catch up to him and try to stop him but it's still no use. The turtles ready to give up head back home but Casey suggests that if the ooze turned him into Dogpound maybe it can turn him back and so they go and get the containers of ooze they have in the sewer but when they use it on Dogpound it doesn't turn him human again but kills him. The turtles return to the sewer where Splinter tells them sometimes killing is the only way but to refrain from it.
