You need to find Graveler in Pokémon Pokopia to complete a request made by Machoke in Rocky Ridge. The beefy fighting-type Pokémon asks Ditto to find its workout pal and, as with all the other Pokémon in this game, Graveler will only appear in a specific habitat which you must put together. Going through the work of completing Machoke’s request not only helps the two buddies meet but also unlocks a new ability for Ditto.
