In the titular short, Bongo was a circus star, loved by people who came from miles around to watch him perform, but the owners of the circus treated him rather shabbily. Then one day, he ran away from the circus into the wild, where he meets his love, Lulubelle.
Eventually he meets her jealous fiance, Lumpjaw, the meanest, toughest bear in the whole forest. When he confronts Lumpjaw, he is chased all the way to the raging river, which gave way to a waterfall, from which Lumpjaw falls, and Bongo is hailed as a hero by the other bears in the forest.
Bongo had a short career in comics in the fifties, notably appearing in comic books Walt Disney's Comics and Stories and Walt Disney's Silly Symphonies. Contrary to the original film, Bongo, Lumpjaw and Lulubelle often talked in those comics. Nowadays he has disappeared of both American and Italian comic productions but still appears in Dutch comics (much like other "forgotten" Disney comic characters such as Brer Rabbit). He also makes a short cameo with Lumpjaw in the last panel of the story This is your life, Donald Duck (Inducks W OS 1109-02), like other Disney characters like Captain Hook, Huey, Dewey, and Louie Duck, Goliath II…
Bongo and Lulubelle made semi-regular appearances at the Disney theme parks up until the 1990s. They notably make a cameo appearance with Brer Bear and two of the Country Bears in The Muppets at Walt Disney World, as an audience for Fozzie Bear's stand-up comedy act.
