Out of the four Pokemon to receive a new Galarian Form within the Crown Tundra - Articuno, Zapdos, Moltres, and Slowking - only one of them has the ability to be evolved into. Obviously, this has to be Slowking, as the other three are Legendary Pokemon that cannot evolve. When you first purchase the Pokemon Sword & Shield Expansion Pass, an event will occur at the Wedgehurst Train Station. In this event, you will actually be able to catch Galarian Slowpoke. Even if you don't, Galarian Slowpoke is rather common on the Isle of Armor.
In order to obtain a Galarian Slowking - the only Galarian Evolution on the Crown Tundra - players will first have to search and find fifteen Galarica Twigs. These are still a pretty common item, found at the base of most trees. Once you have fifteen Galarica Twigs, head to Roaring-Sea Caves via the Frigid Sea Entrance within the Crown Tundra. Here, you will find a young lady that will be willing to turn your fifteen Galarica Twigs into a Galarica Wreath. This is the item that players can use to evolve Galarian Slowpoke into Galarian Slowking simply by accessing it within their bag and having Galarian Slowpoke within their Party.
