Shiny Tepig Pokémon GO is a special version of the Fire type Unova starter. Here's how to look for a Shiny Tepig in Pokémon GO.
If you've got Unova Week on the mind, you'll be glad to know that Pokémon like Tepig will be easier to find in the wild. You can use this as your chance to go Shiny hunting.
Shiny Tepig Pokémon GO: How to Catch
Unlike Community Day events, Unova Week won't feature any increased Shiny rates. You'll still be fighting the normal Shiny encounter rate of roughly on in 450 encounters. There are no boosts to Shiny Tepig this week, but you'll have more luck locating Tepig in general. Otherwise, you could wait for a Community Day that features Tepig.
Shiny Pokémon don't appear on the map as Shiny. You'll have to engage each Tepig you find. When you do encounter a Shiny, you'll get a sparkle and a marker next to the Pokémon's name.
A Shiny Tepig is yellow rather than orange, and its tail and snout are pink. A Shiny Tepig will be worth finding to evolve into Emboar, which has blue flames when Shiny.
In battle, Emboar is slightly outclassed by other Fire and Fighting starter Pokémon like Blaziken. There's no replacing nostalgia, though, so use whichever Fire/Fighting starter you like the most.
