"The Werewolf of Fever Swamp is the eighteenth and nineteenth episode of season one of the Goosebumps TV series. Part one and two premiered on May 17, 1996 on Fox Kids Network respectively.



Grady and Emily didn't want to move to the Florida swamps in the first place, but their mom and dad – both scientists – said that it would be "an adventure they would never forget". That's for sure! First came the horrific howls during the night. Then there was the scary shadow lurking behind the tree and the spooky sounds coming from the swamp. Now Grady can't stop thinking about the spooky hermit who chased him and his new friend Will while they were exploring the swamp behind his new house. And the almost-human howls that make him sit straight up in bed each night. Could Grady's new dog be responsible for some of the midnight mischief? He does sort of resemble a wolf, and he appeared out of nowhere. Everyone is convinced that the dog is a monster, but Grady knows better. Dogs don't howl at the full moon, or disappear at midnight, or turn into werewolves… Do they?

Differences from the book

  • In the episode the dog is named Vandal, not Wolf.
  • Cassie O'Rourke is omitted from the episode.
  • The episode reveals that Will had killed the Swmap Hermit's wife and children.
  • The Swamp Hermit is implied to have died in the episode, while he survived in the book.
  • The ending in the episode is slightly different from the book. In the book, Grady transforms into the werewolf and runs into the swamp with Wolf. In the episode, Grady walks outside and suddenly howls at the moon, but the viewer doesn't see his transformation.
  • Will is portrayed more sympathetically, and Grady says "Poor Will" when he dies.
