Tween Wolf is the second segment of the fourth episode of The Grim Adventures of Billy & Mandy.


After Grim fails to pull a werewolf out of his hat, Irwin is bitten by said werewolf. Then, Billy takes Irwin as his new pet dog, he asks his mother if he can keep the "puppy," but she refuses. Billy asks his father if he can keep the so called puppy. His father, not paying attention, says yes. Billy names the "dog" Sprinkles, and enters him in the Endsville Dog Show to compete against Mandy's dog, Saliva. At the contest, Sprinkles is about to win, so Grim releases a "were-flea" whose bite causes the werewolf to revert to a naked Irwin. In the end, it appears that Irwin won the contest anyway.

  • The title is a parody of the 80's cartoon Teen Wolf
  • The werewolf that bit Irwin was never caught, leaving it a loose end. Although, given the loose continuity of the show, it seems hardly likely that it would ever become a recurring issue.
