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.
