Every year, during the Mushroom Festival, someone falls victim to a voracious monster mushroom. It cuts them open, takes out the innards, feeds on them and impales his victim's dead bodies with a wooden log. Happyshroom seems to take the appearance of a mushroom, similar to Fun Fungal. Happyshroom's cap is dirty red with dirty white edges and spots on it, as well some holes. The suit head is worn down by the weather and the environment of the forest, turning the head almost black.
