Olimar's Notes Swarming Sheargrubs- Mandiblard Family: These Sheargrubs are often speculated to be female Shearwigs, though no absolute answer has been found. These creatures are at the bottom of the food chain, so they swarm at the first sight of danger. They often leech on nectar and plants. This type of Sheargrub is out getting food for the larva. Louie's Notes: Stir Fry then serve.
