Super Rhino is a Disney animated short film based on the characters of the film Bolt. It is directed by Nathan Greno and has Miley Cyrus and Mark Walton in the voices of the main characters.

The short features the first appearance of Penny Forrester as a damsel in distress.

Story
Bolt the dog and its owner Penny have been captured by supervillain Dr. Calico, they are suspended above a pit of molten lava and they are slowly lowered to meet their deaths.

Penny and Bolt are bound back to back with metal restraints that cover their whole bodies from ankles to shoulders, and they are gagged with a muzzle.

Their only hope is Rhino, a fat hamster and their friend, who is endowed with superpowers in order to save them, and the brave hamster makes little effort to defeat hundreds of rivals with all kind of high tech weapons thanks to his new abilities.

He cuts the cable holding Penny and Blot over the lava with a rocket and uses his super strength to catch them in mid air and set them free.

After the adventure ends, we learn Rhino was just dreaming this adventure, and that he never actually had powers or had to save his friends from any distress.
