It uses its big jaws to dig nests into the forest floor, and it loves to feed on sweet tree sap.
Shield
Its natural enemies, like Rookidee, may flee rather than risk getting caught in its large mandibles that can snap thick tree branches.
Sword
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.
Ultra Moon
If you find its nest, you shouldn’t stick your hand inside. You’ll get bitten by an irritated Grubbin.
Ultra Sun
They often gather near places frequented by electric Pokémon in order to avoid being attacked by bird Pokémon.
Moon
Its strong jaw enables it to scrape trees and slurp out the sap. It normally lives underground.
