Joe was fascinated by his fish that would jump in its bowl whenever he tapped on the glass. However, when Joe's friend and mother tried it, the fish did nothing. Confused and upset, Joe continued tapping frantically until the fish jumped out of the bowl. Strange things then started happening - three new vicious fish appeared and brutally attacked Joe's original fish, tearing it apart but leaving it still alive. The fish was then swallowed whole by one of the attackers. When Joe stopped tapping, his original fish mysteriously reappeared in a new bowl.
