They will do most anything Two-Brains tells them to, though perhaps a bit too literally (for example, when Two-Brains tells them to obey the next person to wear his lab coat while he is gone in "Crime Takes a Holiday" and Glen - by a series of occurances - gets his lab coat, they disobey further orders from their real boss in favor of obeying Glen). In addition to being fond of animals, the henchmen are excited by events and fun things such as vacations, fishing trips, and barbershop quartet competitions, thus further dampening their villainous image.
