The Fragglewump is a type of troll from Scotland featured in Hellboy II: The Golden Army. They are grey, twisted creatures with long spindly limbs, though using their glamour they are able to hide their appearance. They have an intense fear of canaries.
While searching for the Troll Market, Hellboy, Abe and Johann found a Fragglewump Cat Seller. By threatening it with a canary, they were able to make it lead them to the Troll Market. When it refused to tell them how to gain entrance, Hellboy backhanded the creature into a wall.
