Shearwood

Shearwoods are large Shearwigs that are made out of wood. One is the boss of Oak Cave, the third cave. Afterwords, they can be found as rare enemies. They attack by dropping logs on your Pikmin, as well as eating them. They have a large amount of health, and can summon Male Sheargrubs to the area. However, it is slow, and if you attack it from behind it should not be a threat. If its health is low, it flies to try to heal. Only Yellows can reach it then.
