Saturday Morning Cartoon: Revolt in the Fifth Dimension
Smoke some Salvia Divinorum if you have it, 'cause here's the infamous Spider-Man episode that ABC never aired a second time, most likely because it's a terrifying drug-soaked phantasmagoria.
Much of the artwork and voice tracks were re-used from an episode of Rocket Robin Hood, which was produced by the same animation studio. The experimental music was a track titled "LSD", licensed from the KPM music library. This and more Spider-Man library music can be listened to here on a Futurechimp playlist.
