King Crawmad

The King Crawmad is a large, lobster-like enemy in Pikmin Z. It holds a resemblance to a Hermit Crawmad, but with a set of large claws, and a blue tint in scale.

Biology
The King Crawmad is the largest species of Crawmad ever known. During the fight, it will constantly attempt to grab you and your Pikmin, crushing them in the process. It can also create tremors and waves by slamming its claws into the ground. While fighting underwater, it can't swim, but is still able to launch out of the water.
 * diet: medium animals, including other Crawmads
 * predators: N/A

Piklopedia Entry
''King Crawmads can grow to gigantic sizes, towering over its own kind. This species has been known to attack and devour other species of Crawmad. I can guess this is to show who's on top of the food chain in the Crawmad world.''

Strategy
Only Blue Pikmin can be able to fight the King Crawmad once it is released into the area. For most of the fight, you're unable to harm it. You're going to have to make it launch at you on one of the mangrove trees, which will make it spin over onto its back, exposing it's tender underside. Throw your pikmin onto it then, but it will quickly shake you off after a bit. Continue this process until it falls dead.
