Rhino is a hamster and the secondary tritagonist in the 2008 hit Bolt. He is Bolt's #1 fan -- he's all but memorized every episode of the canine's TV show. So when Bolt shows up at his door, Rhino sallies forth in his hamster ball to help him out.
He is also not very bright at times.
Rhino was also the central protagonist of his own short, Super Rhino, in which he got superpowers himself by Penny's father (just like Bolt) Near the end of his short, Rhino was onstage singing "The Best of Both Worlds", to a hundred of fans who like him. But then, it turns out he was only dreaming.
He will reappear in Bolt 2: Thunder Strikes! (Sequel)
