Ogden Ostrich, Holey Moley, and Sheldon S. Cargo drive around the world in a van with their own underground pirate television station. Channel Umptee-3, which exists between other channels and is broadcast from a mobile station, tries to focus on a specific topic in each episode, but is usually diverted from it and shifted onto another topic; e.g., one episode started out discussing cats, but quickly segued into the subject of ownership. Meanwhile, "The Frumps" would try to shut the station down or increase their own power, but whatever plan they came up with would fail. The show made great use of stock footage, as did the earlier WB show Freakazoid! Also, the show sometimes made references to well-known movies and TV shows; e.g., the episode "Yours, Mine, and Ours" included references to Cats, Harvey, Star Wars, Dragnet, and The People’s Court, and the title was that of a classic movie.
Characters
The Umptees
Ogden O. Ostrich – An excitable yellow ostrich who first came up with the idea for a television program to show everyone that "the world is a magical place" after pulling his head out of the ground one day and looking at the world around him. At the start of every episode, Ogden comes running up the camera yelling "Hey!" over and over.
Holey Moley – A pantomime character. He is a large mole who carries a number of portable holes that allow him and his friends to go anywhere.
Sheldon S. Cargo – A large pinksnail whose shell is fitted with a unicycle-like wheel to help him get around. Sheldon is the serious, professional member of the team; he tries his best to hold the show together, despite Ogden's almost hyperactive behavior. His name is derived from "escargot."
Professor Edwin I. Relevant – The station's resident expert on everything. Ogden and the others turn to Professor Relevant for information on the day's topic in almost every episode.
Test and Polly – two newscasters who work for Channel Umptee-3.
The Frumps
Stickley Rickets – The elderly president of a corporation that produces boxes. Because the "Umptee-doodies" encourage people to take things out of boxes and look at them in a new way, he sees them as a threat to his business. So he constantly plots to shut them down and "put them in a box, where they belong."
Pandora Rickets – Stickley's wife. She is not nearly as obsessed as her husband where the Umptees are concerned. Pandora even likes to watch some of the shows, although she does not want Stickley to find out. Her name is derived from "Pandora's box."
Ed and Bud – Two black-suited henchmen who carry out Stickley's orders and are almost never successful. Ed is the taller one, and Bud is the shorter, balding one.

Due to the short run and general obscurity of Channel Umptee-3, only four episodes and the intro music have been found publicly after its initial airing. Originally, the second, third, tenth and twelfth episodes were posted to YouTube, but they were blocked worldwide by Sony Pictures, leading them to be posted elsewhere, ultimately on the Internet Archive. Currently, Sony Pictures Television has the full rights to Channel Umptee-3, and has the option to provide the series for streaming content providers., it is not yet available on any streaming platform.
