"The Scooby-Doo Project" was a parody of the horror film "The Blair Witch Project", the episode originally aired on October 31 of 1999, scenes of it were shown between episodes of a Halloween marathon the channel was holding, the full episode aired at the end of it and it never saw the light of day again
recently the network celebrated their 30th anniversary and they have started making available old shows that aired on it, this was one of the most requested episodes by fans
i was still a baby when this aired so i only know about it because i heard other people talking about it, these past years on the internet many have claimed to had watched the episode but never found footage anywhere so most of them simply assumed it was just their imagination, recently it became a popular topic in the lost media community
honestly it doesn't seems super scary to me but if i was a child in the late 90s watching this alone at night i think i definitely would be terrified by it
