Amoonguss evolution

Pokémon GO has no evolution levels: a Pokémon evolves when you spend Candy on it (sometimes with an item or a task), at any level.

Amoonguss evolves from Foongus for 50 Foongus Candy.

Amoonguss is the last stage of its family: it does not evolve further.

Family: Foongus · Amoonguss
