Cladshell Pillarking

This Boss first appears in The Plains of Faith in Pikmin: The Final Frontier. It is basically a gigantic catterpillar with hardened Mortar covering its back, hence the "cladshell". This boss makes a second appearance in The Land of Trials. When this boss is first defeated, it will drop the Instant Booster, which will increase the speed of your captains.

How to defeat
To beat this creature, you must throw Granite Pikmin to destroy the mortar shell on its back. Once its back is exposed, chuck any type of pikmin at it to defeat it. However, once its health is low, it will shake of your pikmin and then jump and hit the ground to crush them. Once the mortar omn its back is almost entirely gone, it will then run around the arena in a rampage.
