Rockhopper is a famous mascot in Club Penguin. He has a puffle named Yarr, which was the first red puffle discovered. In December 2007, Rockhopper gave a present, which was to donate red puffles to the Pet Shop. He can be found in many parties and events, like the Holiday Party.

Rockhopper was first shown to Club Penguin in 2006 waddling around the island. He had not met Yarr or discovered Yarr yet, but was sure to penguins that he was a pirate
