Pokédex entries

What each game says about it, in the games' own words.

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.

Names in other languages

Official data here is present-day reference data from PokéAPI, not a snapshot of any one game's era — the Fairy type and hidden abilities arrived partway through the series, so a difference against an older game can belong to the series rather than to that ROM hack.
