Segmented Crawbster

The Segmented Crawbster is a boss on Pikmin 2. It is the boss of the Cavern of Chaos (in the Wistful Wild area). It resembles a large, white larva with a lobster head and a claw. It will attack by curling up and rolling at the Pikmin. Its secondary attack is to slam the ground with its claw and make rocks fall down.

The only way to defeat it is to guide it into a wall, making it hit the wall. This will send it onto its back, revealing its weak point as its stomach (which should not be hard to miss). Throw Pikmin at its stomach to hurt it. After a few seconds, it will get back up and resume attacking. Continue this strategy until it dies.
