Animation for the show was done using a process involving Adobe software Illustrator, Flash and After Effects. McCracken directed, executive produced and story edited the series. Most of the episodes were produced at the Cartoon Network Studios in Burbank, California, while the rest were produced at Boulder Media Limited in Dublin, Ireland. The theme song was composed by James L. Venable, who had originally collaborated with McCracken on "The Powerpuff Girls". Craig described the music as "psychedelic ragtime". Additional music was composed by Venable and Jennifer Kes Remington.
