Grey Goblins were a variety of goblin with a bulbous head and sharp nose. Physically, they resembled Fourthlings more than any other species of goblin. Though lacking in strength, Grey Goblins hunted and fought in packs and sometimes exhibited strong, seemingly unprovoked aggression. During the events of Clash of the Sky Galleons, Grey Goblins attacked the Galerider and killed Sagbutt and Filbus Queep.
