The story of Yogi bear tooks place mostly in the Jellystone park, a caricature of the Yellowstone park name. Yogi's name is commonly seen as a nod to the famed baseball star Yogi Berra. The plot of most of Yogi's cartoons centered on his antics in the fictional Jellystone Park, a takeoff on the famous Yellowstone National Park. Yogi, accompanied by his constant companion Boo-Boo Bear, would often try to steal picnic baskets from campers in the park, much to the displeasure of Park Ranger Smith. Yogi's girlfriend, Cindy Bear, sometimes appeared and usually disapproved of Yogi's antics.
The name "Jellystone Park" and the concept of a hungry bear who steals campers' food was a theme of an MGM animated short titled Barney's Hungry Cousin which had debuted in 1953
