Grubbin

Sun: Its strong jaw enables it to scrape trees and slurp out the sap. It normally lives underground.

Moon: They often gather near places frequented by electric Pokémon in order to avoid being attacked by bird Pokémon.

Ultra Sun: If you find its nest, you shouldn’t stick your hand inside. You’ll get bitten by an irritated Grubbin.

Ultra Moon: It spits a sticky thread to stop opponents in their tracks, and then it grabs them in its sharp, sturdy mandibles to take them down.

Sword: Its natural enemies, like Rookidee, may flee rather than risk getting caught in its large mandibles that can snap thick tree branches.

Shield: It uses its big jaws to dig nests into the forest floor, and it loves to feed on sweet tree sap.
