Richie's Artificial Planet was a Richie Rich Gems segment that aired in the 11th episode of the first season of the Richie Rich animated series. It was based on a two-page story originally published in a 1978 issue of Richie Rich Riches (not to be confused with the 7-minute animated segment of the same name). When produced for TV, it was most recently published in Richie Rich Best of the Years Digest #6 (the final issue of such title) earlier in 1980.
Reggie Van Dough had woken up from a nap, and Richie showed him around the area. Reggie was wondering where they were and wanted to go home. When Richie told Reggie that they were on an artificial planet with earth-style atmosphere, and a spaceship was going to take them home, Reggie was surprised.
