Pokémon #591 in the National PokéDex, a dual type Grass/Poison Pokémon.
Amoonguss is a mushroom-like Pokémon with a large, light-colored Poké Ball designed cap with warts. It also has a huge gray, stem-like body, fierce looking eyes and a large pink mouth. Amoonguss wields two Poké Ball-like shields. It uses the Poké Ball-like patterns on its arms to lure in prey, though it doesn't work too well in most cases. Amoonguss is a carnivore which can be found mainly in long grass, as only their mushroom cap head protrudes from it, generally close to water.
It evolves from Foongus.
