Lipidon

The Lipodon is a gigantic fat-covered Breadbug that swallows objects instead of carrying them. It will eat any metal objects or enemies that are on the ground or being carried by Pikmin. It will eventually go back to its nest, and all the metal, enemies, and Pikmin it has eaten will be digested and you will need to reset or exit the cave to get the metal back. The Lipodon can be damaged at any time. Once it is defeated, it will spit out everything it has eaten, but it will not stay down for long. You will need to carry it back to your ship before it wakes up.
