Stucky is not an official member of the Ham-Ham Clubhouse, but he is best friends with Cappy! Stucky gets his name from becoming stuck in a plastic pipe. He couldn't wiggle himself free, but at that point, he decided to just roll with it and carry on with a smile on his face, figuratively and literally! His only forms of movement are running and rolling around, all while saying "Roly-poly". This cheerful and playful hamster's favorite game to play is hide-and-go-seek and is really good at it, too! In this episode, Stucky ends up meeting a cute white bunny rabbit and develops a crush on it. The only problem with it is, that the white bunny is actually a fakie-toy! Worried about how Stucky might feel when he finds out the truth, the Ham-Hams decide to work together to try and make sure Stucky doesn't find out the truth until he possibly loses interest in that said toy rabbit.

(For Stucky's voice, I will allow his to either sound similar or identical to his previous high-pitched child voice provided by Jillian Michaels. I'm actually looking for a female to voice this young hamster that's stuck in a plastic pipe because of that. Here are some clips of Stucky's only official English dub Hamtaro episode for voice reference!)
