Wolf gravy is a condiment of unknown origin that is used on food, which magically transforms anyone who eats it into a werewolf by the light of the full moon. It was used by Radna in the cartoon show episode "Wolf In Peewit's Clothing" to turn his visitor Peewit into a werewolf so that he could capture a few Smurfs for restoring Radna's magical abilities. Peewit was restored to his human form with the help of Sir Johan and the Smurfs when he was given a garlic bud to eat while he was still a werewolf. Greedy Smurf accidentally ate some of the gravy and was changed into a weresmurf until he was given a garlic bud to eat.
