Yo Yogi! featured the gang as young teenagers (Yogi, Boo Boo, Huck, Snagglepuss & Cindy). They worked for the LAF (Lost & Found) detective agency which was run by head security agent John Smith (later the park ranger), over @ Jellystone Mall (owned by Doggie Daddy & Augie Doggie).
Causing trouble were teenage Dick Dastardly & his pup, Muttley, along with Roxy Bear.
In the middle of the show's run, Kellogg's cereals offered 3-D glasses in which some scenes in an episode would be in 3-D. To signify when to put the 3-D glasses on, Yogi would spin his hat.
