Kevin Keene encountered Loafer after sinking into a quicksand pit that led to an underground cavern. Kevin's Power Pad was out of power, and he was convinced that he'd be alligator food until Bayou Billy showed up and called Loafer off.
According to Bayou Billy, Loafer gets awful indigestion from eating strangers. He also has at least three offspring, which are seen chasing Duke away from his nest.
In a later episode, Loafer accompanied his owner to a ball at the Palace of Power.
