“Let it begin! Let it begin! LET IT BEGIN!!!”
- Rhino

Rhino is a hamster that Bolt and Mittens meet while trying to get food. He watches all of Bolt's episodes on TV, and claims himself to be Bolt's number one fan. Though he was at first living with an older woman in a trailer park among many other hamsters, he decides to join Bolt in his journey to find Penny. He is the one who convinces Bolt that even if he isn't a superdog, he is still a hero. He also tells Mittens that you should never abandon a friend, even if they think they don't need help. He is adopted at the end of the movie by Penny and her mother.
