Shiny Pokémon

Shiny Pokémon, often called shinies, are alternate colorations of Pokémon. Shiny Pokémon are a feature that existed starting in PMU 6, and to staff in early PMU 7. They were discontinued, and then re-added to PMU 7 on the 19th of September in 2019. Using a Legendary/Mythical cosmetic item on a shiny Pokémon will in turn make the disguise appear shiny as well.

PMU 6
In PMU 6 select wild Pokémon had a chance of being shiny. Shiny Pokémon were most commonly available to players during Holiday Cave and other events.

PMU 7
In PMU 7, shinies were first available during the anniversary Holiday Cave of 2019, with shiny rates for recruitable Pokémon added in other dungeons over time. All Generation 1 to Generation 5 Pokémon (including later introduced evolutions) as well as all Generations' Fossil and starter Pokémon, Alolans, and Noibat are able to be and spawn shiny. Pokémon hatched from Mystery Eggs cannot presently be hatched shiny. The shiny rate of a Pokémon is manually added and determined on its rarity and the difficulty of the dungeon. Pokémon in the overworld that can be recruited can also spawn shiny.

Shiny Pokémon while visibly different also have an asterisk (*) to the right of their name, excluding the name that displays above the sprite. If a shiny Pokémon is on a floor or has spawned, a sound effect (magic838.ogg) will play across the entire map. When in a party, only the party leader will hear this if the shiny Pokémon spawned on floor entry. A player can also turn their active Pokémon shiny with use of a Sparkle Token, a single-use item that was available in the shop of anniversary Holiday Cave 2019 and sold during auctions. Sparkle Tokens work on every Pokémon up to Greninja.

Trivia

 * The sound effect for shiny spawns was added on the 21st of October in 2019.
