The book was later adapted into an animated short film from Weston Woods Studios in 1958 and an episode of a PBS Kids TV show of the same name in 2007, but with a few differences, such as George getting his bike repaired by the Renkins.

The director decides to put George in the show as a bugle player and gives him a green coat and cap similar to Bob's.

The show also features an elephant, a rhino, a hippo, a giraffe, a camel, a kangaroo and her joey, a leopard, a sea lion, and a bear cub.

After a struggle to get the bugle out of him, the director angrily scolds George for disobeying him, prohibits him from the show, and makes him sit on a bench until he gets sent home.

While George regrets his mistake, he notices the ostrich pulling a string that allows a cage door to open and the bear cub to escape.
