In the Poetic Edda, Thor recounts an incident where Þjálfi is chased away by she-wolves but gives no additional information about him. In the Prose Edda, Þjálfi and Röskva are the children of peasant farmers. Thor and Loki stay a night at their farmstead and there Thor shares with the family the meat of his goats, Tanngrisnir and Tanngnjóstr. Þjálfi, sucks the marrow from a leg bone from one of the goats. When Thor resurrects the goats the next morning, he finds that one of the goats is lame in the leg and becomes enraged. As a result, Thor maintains Þjálfi and Röskva as his servants.
