That, in turn, means new methods for evolution: the King’s Rock was used for evolving Poliwhirl and Slowpoke in the main Pokémon games by having them hold the item when being traded - a mechanic that’s not in Pokémon Go at all as things stand. So with that in mind, how do you evolve Poliwhirl into Politoed, and evolve Slowpoke into Slowking, and likewise how do you get the King’s Rock in Pokémon Go? On this page: If you were interested in other special evolution items, there is the Sinnoh Stone, Metal Coat, Dragon Scale, Sun Stone, and the Up-Grade. There’s no guaranteeing which evolution item you’ll get, but with only a handful in the game, at least you hopefully shouldn’t have to wait too long to get a hold of all the items you need. If you are playing during the A Very Slow Discovery event in June 2021, know you can get a King’s Rock as part of the ‘Evolve a Pokémon’ research task, and one for free from the weekly Event Box in the shop. Here in Pokémon Go, it’s far easier: simply find yourself a King’s Rock and use both that, and some Candy like usual, to evolve it into Politoed from the same in-game menu you’d use to evolve a Pokémon normally.
Poliwhirl to Politoed Evolution cost - 1 King’s Rock and 100 Poliwag Candy.
The Season of Mythical Wishes continues with the Winter Holiday event, which has brought Mega Glalie to Pokémon Go. Don’t forget to partake in the new Go Battle League season.
Elsewhere, be sure to use Daily Adventure Incense for the chance of encountering Galarian Articuno, Galarian Zapdos and Galarian Moltres.
Like the evolution chain above, Slowking comes as a branching evolution from Slowpoke, acting as an alternative to Slowbro. Interestingly, as you’ll see in our best Pokémon in Pokémon Go listings, both Slowbro and Slowking have identical stats, meaning the choice to evolve for one or the other is purely down to your personal preference - and for completing your Pokédex, of course.
Again, as above, to evolve your Slowpoke into a Slowking simply use your stored up Candy, and a King’s Rock, to evolve it via the usual in-game menus.
Slowpoke to Slowking Evolution cost - 1 King’s Rock and 50 Slowpoke Candy.
