Shellder, the water-type bivalve Pokémon from Kanto, can be found in the wild in Pokémon Go. Yes, Shellder can be shiny in Pokémon Go!
Cloyster doesn’t see much use in raids, as there’s many ice- and water-type Pokémon that do significantly more damage than it. However, Cloyster does see some usage in Ultra League PvP at times.
Other than that, though, these are just cute Pokédex fillers with pretty good shiny versions.
What is the shiny rate for Shellder in Pokémon Go?
As per The Silph Road, the shiny rate for Pokémon on a regular day is approximately one in 500. Shellder is not a Pokémon that gets a “permaboost” (meaning that it’s a rare spawn and thus gets a boosted shiny rate).
What can I do to attract more shiny Pokémon?
Not much, unfortunately. It appears to be random chance. Shiny Pokémon catch rates are set by developer Niantic, and they are typically only boosted during special events like Community Days or Safari Zones, or in Legendary Raids. There are no consumable items that boost shiny Pokémon rates.
Where can I find a list of available shiny Pokémon?
LeekDuck keeps a list of currently available shiny Pokémon. It’s a helpful visual guide that illustrates what all of the existing shiny Pokémon look like.
