[9] Members of the production staff have voiced several characters throughout the series, including Minty Lewis, Toby Jones, Andress Salaff, and Matt Price.

The series regularly used guest voice actors for recurring characters, such as Steven Blum, Courtenay Taylor, David Ogden Stiers, Robin Atkin Downes, Jeff Bennett, Jennifer Hale, David Kaye, Fred Tatasciore, Matthew Yang King, and Julian Holloway.

Although Cintiqs were initially optioned to be used for the show, Quintel stated that he felt more comfortable working on paper, considering it to be more organic and more representative of each artist's individual style.

Board artist Calvin Wong said, "the tools of the trade as being pencils, pens, white-out, and occasionally lightboxes and electric erasers".

[46] Lumbrad ended his review by recommending the show and calling it "one truly awesome cartoon with a lot of good humor to enjoy".

Studios announced that it would develop a comic book series based on the show and that KC Green would be writing the script and Allison Strejlav would be in charge of the illustrations.
