Henry the duck's awful mistake is to go after the ant that turns up in his kitchen as he prepares a meal for his friend Clara. When the ant runs into a crack in the wall, Henry takes a hammer to the wall . . . and then goes after the pipe behind the wall where the ant has taken refuge. The resulting disasters begin with a spilled supper and end with a flood that washes away Henry's house. Then, settled in a new house just-like-that, Henry again asks Clara to supper, again spots an ant, but this time ""He looked the other way!"" But it takes more than a hammer and chaos to make a joke, even at Quackenbush's one-dimensional level.
