Wackyland, the bizarre world from which Gogo-Dodo comes, wasn't created for this show; it first appeared in a little known Looney Tunes short named Porky en Locolandia (1938), which also featured a dodo that looked and acted exactly like Gogo Dodo from this show.
According to Maurice LaMarche, in a segment where Babs impersonated Plucky, Dizzy, Shirley, and Fifi, Tress MacNeille's performance was so accurate for those characters, the voice actors and actresses (LaMarche, Joe Alaskey, Gail Matthius, and Kath Soucie) were worried that the studio would fire them and have MacNeille replace them all.
Season two episode eight, "Buster and Babs Go Hawaiian (1991)" was co-written by three then-teenage girls (Renee Carter, Sarah Creef, and Amy Crosby) , who just happened to be fans of the series.
The show's theme song is sampled for the theme song of Harry the Bunny, a series in the BabyFirst channel.
