Hamelin demon was a species of symbiotic demons, who trapped its victims in their dimension with illusions based on the individual childhood's dream.


A Hamelin demon infested a building in Tenderloin, San Francisco. It targeted children on the verge of losing their childhood, making 25 children disappear in three decades. The sound of the trapped children scared out the residents' building, and the landlord contacted detective Robert Dowling.

The Scoobies then went to exorcise what they believed to be a haunting, but the demon attacked and trapped them in its dimension, with a collective illusion based on their respective childhood's dreams. Despite temporally modifying their memories, they were able to free themselves and the missing children by refusing the reality the demon created.

Behind the Scenes

  • Hamelin's name is based on the tale of the Pied Piper of Hamelin, which tragically ends with the piper attracting children away from the city.
