- Back when the series was in development in 2004, the planned series was somewhat different. Background designer Brad Graham was originally slated to do the character designs & backgrounds. The character designs looked completely different, and had more of a conventional "abstract" look like most modern kids' cartoons, but many of Graham's elements remained in the final version. The more diverse Grossology team lineup consisted of Abby & Ty (who were still the main characters, only Abby had pigtails rather than the long trademark ponytail), Nigel Stodding (a British kid fashioned like 1960s secret agent Harry Palmer), Lab Rat (who was an overweight Caucasian boy, but still had Hermes, who looked somewhat identical to the final version), and a weirder assortment of kids including Pink Eye (a beatnik boy; the basis for the villain Roger Pink-Eye), Creepy Crawly (a goth girl with spiders, who may have been the basis for the adult villainess Insectiva.), Sloppy Joe (a dirty spud-shaped kid, who ultimately became an adult villain for the series) and Colin Polyp (A bulb-headed kid who may have evolved into the adult villain Dr. Cornelius Colon in the final series). Abby & Ty still went to Ringworm Junior High School (which looked like a more classic-style school than the more modern one in the series), and the Gag Lab was originally a more complex underground secret base called the Grossotorium (something along the lines of the titular lab of the TV series, Dexter's Laboratory). Abby and Ty did not wear Slime Suits at this point (that may have been devised upon the success of Pixar's The Incredibles).
