Dag purchases a "white ant farm" and unwittingly releases a colony of termites who slowly devour the dam. The Beaver Boys fight over who gets the first bite a rare, ancient oak tree that fall into their dam. Irritated at first, Dag then calms down when Norm is suddenly transformed into a beaver toddler. Not to be outdone, takes a bite and joins Norbert in beaver tot land. The damn becomes a whole new world as the two brothers go from one argument to the next.
