To evolve your Galarian Slowpoke into a Slowbro, you’ll have to collect Galarica Twigs from around the Isle of Armor and bring them to a trader in the Workout Sea.
Slowpoke is the only Pokémon in the Sword and Shield expansion, Isle of Armor, to get a new Galarian form.
You can find the yellow-headed Pokémon roaming around beaches on the Isle of Armor. To evolve it into the gun-toting Galarian Slowbro, you’ll need a Galarica Cuff. These can be obtained from a female NPC sitting on an island in the Workout Sea.
