Rockhopper (commonly abbreviated as RH as a slang term from Club Penguin players or Captain Rockhopper) is a friendly pirate who docks at irregular intervals at Club Penguin Island; usually with gifts, puffles, or knowledge

His ship is only docked at the Beach on special Club Penguin parties or events. He keeps a journal of his adventures, and sells rare items brought over from Rockhopper Island and other places. When he comes to Club Penguin Island, he gives away a free item and sells other items to member penguins in the Rockhopper's Rare Items catalog. The catalog includes items such as pirate hats like the Puffle Bandana, telescopes, backgrounds, furniture, and other items
