The three Guardians of the Lake have flown all the way from Sinnoh to our world. Players now have a very rare chance to encounter Uxie, Mesprit and Azelf while using Pokémon GO (iOS/Android).Results of Azelf being encountered in America have already been made. Currently it is unclear if there is any regional mechanic to the trio’s release.UPDATE: It appears both Shellos variations are now spawning as well! These cute little sea slugs may be appearing near you, so keep your eyes peeled!Shellos have mysteriously vanished from the game. Whether or not they will return in a timely matter has yet to be seen.Do you have a favorite of the trio? Let us know in the comments!
