According to series writer Paul Dini, Gogo is the only member of the Tiny Toon Adventures cast who was a relative of one of the Looney Tunes characters; in this case, Gogo was the son of the original dodo from the 1938 Looney Tunes cartoon Porky in Wackyland.
Gogo is noted for performing various bizarre sight gags or stunts. Furthering this end, Gogo made his home in the Daliesque realm known as Wackyland, a surreal land where backgrounds changed constantly and the entrance to which was located across a bridge on the outskirts of the city of Acme Acres, the usual setting of Tiny Toon Adventures. Gogo and Wackyland were considered bizarre and nonsensical by even the lax standards of his cast, and the latter was usually explicitly avoided.
In the episode 'Her Wacky Highness', as Babs is bummed out at all of her authority figures telling her she needs to learn self control because of her wackiness, Gogo persuades her to come to Wackyland by means of her television set. He shows her around and eventually they promote her to Queen Babs, first ruler of Wackyland, as Buster, Plucky and Hamton go look for her. Even Babs can not take all the wackiness from them and tells them they need to learn self control, which is forbidden in Wackyland, so they chase after her, along with Buster, Plucky and Hamton. With the help of Gogo Dodo they are able to escape without any harm done and find their way back home to the more sane Acme Acres, where Babs is happy and relieved to return.
Gogo was not only a student at Acme Loo, but also served as a hall monitor and performed other duties, such as acting as a cuckoo bird for the Looniversity's various clocks.
Gogo's end tag credit is "It's been surreal!", then pointing a remote control at the audience and clicking it, as the entire screen goes to black.
