The Dead body (whose name is Stikklebrix) is the corpse of Pikkupstix's assistant, and can be found at white wolf mountain, near the Taverley side. During his supposed task, he was attacked and killed by wolves residing in the mountain. Players can search his dead remains for two wolf bones, required for Wolf Whistle. They cannot do this after the quest has been completed; instead the player will just say 'Poor Stikklebrix. I'm sure that Pikkupstix will mourn your passing'.
The name "Stikklebrix" is a pun on Stickle bricks, a children's toy.
