Slugma, the Lava Pokémon from Johto, is found in the wild Pokémon Go. Yes, Slugma can be shiny Pokémon Go!
You won't see either Slugma or Magcargo used in PvP or PvE content, but it's a pretty good Shiny! It will be a tough decision whether or not to turn your cute silver snail into a bright pink snail.
What is the shiny rate for Slugma in Pokémon Go?
According to old research from the now-defunct website The Silph Road (via Wayback machine), the shiny rate for Pokémon on a normal day is approximately one in 500. Slugma is not a confirmed Pokémon that receives a “permaboost” (meaning that it is a rare spawn and therefore receives an increased shiny rate).
What can I do to attract more shiny Pokémon?
Unfortunately not much. It seems to be a coincidence. Catch rates for Shiny Pokémon are set by developer Niantic and are typically only increased during special events such as Community Days or Safari Zones, or during Legendary Raids. There are no consumable items that increase the rate of Shiny Pokémon.
