A distribution event for a Galarica Wreath in Pokemon Sword & Shield has been postponed, due to a prominent tournament being delayed in South Korea.
Pokemon Sword & Shield introduced Galarian forms, which were alternate versions of existing Pokemon that evolved differently. The Slowpoke line received three Galarian forms in the Expansion Pass for Pokemon Sword & Shield. Galarian Slowpoke has golden patterns on its body, Galarian Slowbro has a Pokemon clamped onto its arm, and Galarian Slowking looks like Darth Vader. Galarian Slowpoke are fairly easy to catch on the Isle of Armor, but evolving them takes a little work. In order to evolve a Galarian Slowking, you need to explore the Isle of Armor and the Crown Tundra and gather fifteen Galarica Twigs. You then need to find the old woman who is hiding in the Roaring-Sea Caves, and give her the twigs. She will weave them into a Galarica Wreath, which can be used to evolve Galarian Slowpoke into Galarian Slowking.
The Pokemon Company has been giving away Mystery Gift item distribution codes, to celebrate online events. The most recent involved giving away a free Gold Bottle Cap. There was another item distribution event planned, where a free Galarica Wreath was going to be given away to celebrate the Pokemon Sword & Shield South Korean Crown Tournament. According to Serebii, this giveaway has been postponed, as the pandemic has resulted in the tournament being canceled. A new release date for the event will be revealed in the future.
Gathering the fifteen Galarica Twigs can be extremely frustrating, as they spawn randomly on the Isle of Armor and the Crown Tundra. It would have been useful to receive one for free, but it's understandable, given the current global situation.
Pokemon Sword & Shield players have received numerous free items through Mystery Gifts since the game launched, including a ton of free cash in the run-up to the release of the Isle of Armor. Fans will just have to wait a little longer for their free Galarica Wreath, or if they really care, they can just go and scour the DLC areas of the game for Galarica Twigs and make one of their own.
