Rocko

Rocko is the tritagonist of The Pebble and the Penguin. He is Hubie's best friend, and a rockhopper penguin.

Trivia

 * He's played by James Belushi.
 * His species is a Northern Rockhopper Penguin.
 * He doesn't like fibs.
 * Rocko was rumored to be the movie's deuteragonist. This isn't true as Marina has as much plans as Hubie.
 * When Rocko "flies" at the end, this is pure on-screen fiction, as it's a world renowned fact that penguins are among a lot of birds that can't fly.
