Howard has an age crisis after being heckled at a gig of he and Vince's. After hearing from Bollo about the Fountain of Youth on Naboo's home planet Xooberon, Howard and Vince steal his amulet and travel there, where they wander the Desert of Nightmares and meet the Xooberon Tribe. Back at the flat, Naboo finds out about Howard and Vince stealing his amulet, and is annoyed that he has to save them. The Xooberon Tribe notice Vince has the amulet and make him their leader, and Howard his slave. Meanwhile, The Hitcher overviews these events, planning to steal the amulet for himself. Vince's status as the Chosen One is tested when a beast named Sandstorm threatens the Xooberon Tribe; Vince befriends him by gifting him with gloves which he uses to masturbate. Howard is tricked into stealing the amulet by The Hitcher, who knocks Howard out and leaves. He awakens with Vince, buried up to their necks in sand; a punishment from the Xooberon Tribe for loosing the amulet. Naboo and Bollo arrive, and accompany Vince and Howard to the Fountain of Youth, hindered by an evil tree; whom Vince summons Sandstorm to disposes of. Naboo then flushes the toilet of the Fountain of Youth, liquefying The Hitcher. The King who first gave Naboo the amulet and sent him to earth arrives and congratulates Naboo. On the way back to earth, Howard and Vince consume Youth Juice, which reverts them to babies. (thetvdb.com)
