Gloom is one of the Pokémon that has more than one evolution option in Pokémon GO. Both of Gloom's evolutions require Oddish candies, and one also needs an evolution stone to obtain. There's a small chance that players can encounter Gloom in the wild, but it's more likely an Oddish is found. Oddish can be evolved into Gloom for 25 candies, then Gloom will require an additional 100 candies to evolve.
Gloom is a Grass- and Poison-type Pokémon that can evolve into either Vileplume or Bellossom. Vileplume is also a Grass- and Poison-type Pokémon, but Bellossom is just a Grass-type. For each Gloom evolution in Pokémon GO, players will need 100 candies, and Bellossom also requires a Sun Stone. Players will need to collect a lot of Oddish candies in order to evolve Gloom into Vileplume and Bellossom.

Catching an Oddish will award three candies, but using a Pinap Berry increases it to six, and a Silver Pinap Berry will give players seven candies. One candy can also be earned every time an
