Callen regretted having to take a break from his comic. "The original series was building a somewhat impressive fan base, but I had to stop a while for physical reasons," he said. "I can’t tell you how happy I am to be returning to these characters! My goal with this new book was to produce more of the same quirky stories, but crank up the art a little bit.”
Natural Creatures retains the same format as the Halo and Sprocket comics -- short stories that depict Halo and Sprocket exploring the questions that behavior of humans raises in even the most simple situations while Katie holds her own for human nature against a robot's logic and an angel's divine knowledge. The trio visit Katie's bathroom (why do women shave their legs but not their arms?) and a pet store (why are kittens cuter than lizards?). Sprocket briefly experiences what it is to be human, and Katie learns that it's no easy thing to play a practical joke on an angel.
Halo and Sprocket: Natural Creatures is 72-pages long, available now for pre-order from comic book stores with the Diamond Code MAY083549. A preview of the graphic novel is available at SLG Publishing's website, www.slgcomic.com.
