A race of monsters known as the Disgustoids are banished from society due to their unruly behavior and grotesque appearances. From their sentient and eponymous subterranean mountain fort, they unleash crazy stunts on the public. Their leader, a purple tusked creature depicted wearing a pair of underwear named Festro, is a macho party animal willing to do anything to help out his group, even when his help is less than desired, Festro always. Dingle, a scrawny, blue dog-like monster, who acts as their faithful pet, intelligible only to the group. Slog , a furred proboscis monkey-like monster, is likewise blindly loyal, but lacks critical judgement skills—the more hazardous something is, the more likely he will be to follow it. Gweelok , an acned ball of mucus, has a demanding attitude and an obsession with technology. The Fart, a giant monster made of buttocks who flatulates when touched—is the most sensitive and levelheaded of the group.
