When Bugs welcomes the castaways, he says, "Welcome to Humuhumunukunukuapua'a Island." "Humuhumunukunukuapua'a" is the Hawaiian name for the reef triggerfish, the state fish of Hawaii.
The two castaways are caricatures of writers Tedd Pierce and Michael Maltese (who also provided the voices.)
Wackiki Wabbit notably contains the first experimental use of strongly graphic, nearly abstract backgrounds.
The phrase "Now is the time for every good man to come to the aid of his party" used by Bugs is a filler phrase coined by instructor Charles E. Weller as a typing drill in his 1918 book "The Early History of the Typewriter."
Bugs spoofs both the jungle adventure films (Tarzan type) and Polynesian paradise spectaculars that were popular cinematic themes at the time.
