Rockhopper Cave

Rockhopper Cave is a cave in which Rockhopper stores his treasure. 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. The passage is in the game Hydrohopper. I don't know how, but Billybob e-mailed me this info. I think the the name Hydrohopper is a clue to this passage because it almost says Rockhopper and the game is on a boat sailing away from the island. I have beat this game over 13 times and no Rockhopper island, but Billybob E-mailed me saying that the passage is in the game Hydrohopper. JOKING!!!
