Just as with the main games, the Sun Stone is used for getting your hands on these Pokémon - without it, there’s no other way to add them to your Pokédex. So with that in mind, this page explains how to evolve Gloom into Bellossom, evolve Sunkern into Sunflora, evolve Petilil into Lilligant, evolve Cottonee into Whimsicott and evolve Helioptile into Heliolisk plus how to get a Sun Stone in Pokémon Go? On this page: It’s worth noting that there are several other special evolution items which work in precisely the same way: the Sinnoh Stone, Metal Coat for Steelix and Scizor, the Dragon Scale for Kingdra, the King’s Rock for Slowking and Politoed, and the Up-Grade for Porygon2. Evolution stones themselves haven’t been in the game until the current update - in fact the originals, like the Grass Stone, still aren’t in the game - and so the mechanic itself is new, too. To evolve Gloom into Bellossom, then, you’ll need to get yourself a Sun Stone, along with the required amount of Candy, and simply head to the normal section of the menu where you’d go for evolving the Pokémon and carry on with the usual steps from there.
Gloom to Bellossom Evolution cost - 1 Sun Stone and 100 Oddish Candy.
It turns out you do indeed need the Sun Stone to evolve Sunkern into Sunflora, and that can be done in the usual way from the game’s menus.
Sunkern to Sunflora Evolution cost - 1 Sun Stone and 50 Sunkern Candy.
The use of a Sun Stone applies with the main games, too, so this should come as no surprise.
Petilil to Lilligant Evolution cost - 1 Sun Stone and 50 Petilil Candy.
Cottonee to Whimsicott Evolution cost - 1 Sun Stone and 50 Cottonee Candy.
Helioptile to Heliolisk Evolution Cost - 1 Sun Stone and 50 Helioptile 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.
Fortunately, there is some strategy here after all! A special evolution item will drop on the seventh day of your PokéStop Daily Bonus streak. There’s no guaranteeing which evolution item you’ll get, but with only five in the game at least you hopefully shouldn’t have to wait too long to get a hold of all the items you need.
