The series used several unique production techniques for the period. The aardvark's body was solid blue: his only clothes—a pair of blue shorts and matching T-shirt—were a matching blue. Similarly, Charlie Ant was solid red, and did not sport any clothing. As such, the character's solid colors allowed them to stand out clearly against the multi-colored backgrounds featured prominently in the series. Charlie also sported half-closed eyes, as a sign of a bon viveur.
