Nipper is a gigantic Hermit Crab and a boss in the game Banjo-Kazooie.
Nipper is encountered in the second level of Banjo-Kazooie, Treasure Trove Cove near the entrance of the area. When first approached by Banjo, Nipper will say that he owns the beach and that Banjo doesn't have a chance in finding anything without his help.
Hearing this, a smug Kazooie insults Nipper, angering the giant crustacean and making him attack by swinging his claws violently. Blue Eggs won't hurt Nipper, so players will have to approach him when he takes a rest from swinging his claws and attack his face. After being hit three times, Nipper will be defeated and retreat into his shell, which players can then explore.
