In the second episode of the original 1987 Teenage Mutant Ninja Turtles cartoon, we meet Rocksteady and Bebop, the Shredder’s hench-mutants.
About 18 and a half minutes into the episode, there’s a quick shot where Bebop’s vest — Which is normally red — is accidentally colored yellow. I thought that was a cool look, so I made a custom toy of it. And then I made a mostly-animation-accurate Rocksteady to match, because you can’t just have one of these knuckleheads.
TMNT, Bebop, Rocksteady, and all related characters are owned by Nickelodeon.
