Little Quacker

A baby woodpecker mistakes Jerry for his mother. The mouse rejects the newly hatched bird but soon finds himself protecting it against his feline nemesis, Tom.

Chased by Tom around the barnyard, Jerry takes refuge under a hen, who, in her nest, is sitting on eggs. Tom has to figure out ways to get Jerry out from under the protective hen.

When a duck hatches from the egg underneath Tom, the newborn (Little Quacker) is convinced Tom is his mother. Tom would like to eat the duckling; Jerry is determined to keep that from happening.

Jerry crashes a vase onto Tom's head, which gets Mammy to throw Tom out. Jerry at first revels in his freedom, but soon tires of this, and, under a flag of truce, hatches a plan with Tom.

Tom is duck hunting, and he wings a little duckling that can't quite keep up with the flock. Jerry gets to the fallen duck before Tom, bandages his wing, and shelters him from Tom as he keeps running out to join his flock.

Tom, complete with mortarboard, is teaching a kitten the basics: "cats chase mice." But Jerry keeps subverting this lesson at every opportunity.

Tom's new book on "how to catch a mouse" doesn't prove too helpful against Jerry; actually, Jerry seems to make better use of it than Tom.

Donald shows his nephews the moves that won him his hockey trophy. But the boys have a few moves of their own.

A moment after a bottle of white shoe polish pours on Jerry, Tom hears on the radio that a white mouse, having swallowed an explosive, has escaped from an experimental laboratory and that slightest jar of the mouse could cause it to explode and blow up the entire city. It is then that Tom notices now-white Jerry and concludes it's the escapee.

Tom drowns in a lake and sinks to the bottom. There, he finds a mermouse, which he tries to capture and eat.
