Cartoon Quest

Cartoon Quest was the name of a block of mostly animated television shows that aired on the Sci Fi Channel starting in 1992. Similar to USA's Cartoon Express, it featured reruns of various older cartoons interspersed with interstitial segments; in this case, focusing on a live-action family (all clad in loincloths) exploring a strange region. During its run, the block aired every Saturday from 7:00 AM to 11:00 AM EST.

This block ended in 1995, and was replaced by The Animation Station.
