Rockhopper Cave is a cave in which Rockhopper stores his treasure. He first revealed it to penguins in an exclusive book called "Christmas on Rockhopper Island". The cave is partially connected to a volcano mountain in Rockhopper Island. This proves that Rockhopper Island is both a tropical and a volcanic island.
Trivia

- It is said that the Hidden Treasure Background is set here.
