Shiny Spoink Pokémon GO is available to catch, but only if you're lucky. Spoink will be featured this weekend during the Galarian Mr. Mime event, and will be attracted to Incense more often than usual. you can use this event as your chance to hunt for a Shiny.
Shiny Spoink Pokémon GO: How to Catch
The event will take place Dec. 18-21, and will feature a ticketed Research event. If you don't opt for the premium Research, you'll still be able to enjoy increased Incense spawns for Jynx, Swinub, Spoink, Woobat, Cubchoo, and more.
Shiny Spoink won't have an increased spawn, so you'll be working with the standard Shiny encounter rate for one every 450 encounters. Shiny Pokémon don't appear on the map as Shiny, so you'll have to engage every Spoink you find.
You'll know that the Spoink is Shiny when you see the sparkle over its model and nametag. Of course, the Spoink will be a different color. A Shiny Spoink is unmistakable; its body is tan and has a gray ball.
Spoink evolves into Grumpig, a middling Psychic type defender. It's not awful, but it's also not a first choice when it comes to the many great Psychic types already in the game.
