 Some sitcom style humor was derived by the concept that the Goop-Mandos were required to recharge after missions by hanging upside-down in the large closet in Chris' room.This concept was derived from a small oozing hourglass-like device housed in the lower torso of each Goop-Mando Action Figure.Although the Carter parents never made an appearance on the show (their voices were heard off-screen in a few episodes), Chris' older brother Todd, a vain and surly "valley dude", was constantly suspicious of the extracurricular goings-on around the house.
