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.
An Amoonguss appeared in Foggy Pokémon Orienteering! when its rest was disturbed by Bonnie and Pikachu. Angry to have been woken up, it uses Spore on them and later the other members of Ash's group after they do the same thing.
Amoonguss, the Mushroom Pokémon and the evolved form of Foongus. By swinging its Poké Ball-like arms while dancing, Amoonguss is able to lure its prey.
Bronius owns an Amoonguss where he used it to put Bianca to sleep with Spore. It had a battle with Black's Pignite, Nite, and lost due to the double type-disadvantage.
In the Pocket Monsters BW: The Heroes of Fire and Thunder manga
Amoonguss, along with its pre-evolution, is similar to Voltorb and Electrode in that it resembles a Poké Ball.
However, unlike Voltorb and Electrode, it only has a Poké Ball design on it, instead of being in the shape of one.
Likewise, it features the whole design, complete with the circle resembling the button in the middle (contrary to Voltorb's evolution line having just the shape and general colors, and according to the Pokédex, being transformed Poké Balls themselves).
Amoonguss has the highest HP base stat among all Poison-type Pokémon.
Amoonguss is the only Pokémon with a base stat total of 464.
Origin
It appears to be based on Amanita muscaria or mushrooms of the Agaricus genus, due to it being Poison-type. Its cap and the shield-like arms were designed to look like the front of a Poké Ball.
Name origin
Amoonguss may be a combination of amanita (a genus of mushroom) and fungus or humongous (huge). Together with its pre-evolution, their names are a corruption of the phrase, "Fungus among us."
Morobareru is a combination of もろに moro ni (completely) and ばれる bareru (slang for "[for a secret] to be exposed"), referring to how it no longer convincingly looks like a Poké Ball.
