Plot

Sylvester Cat spots Tweety Bird in a display window of an after-hours department store and sneaks inside through a mail server chute. Tweety flees Sylvester by hiding in a hat pile and a doll house, evades the shots from a rifle Sylvester uses, and escapes in a vacuum tube. Tweety sends a dynamite stick through another tube, and Sylvester swallows it, thinking it is Tweety. The dynamite blows up inside Sylvester after the cat leaves the store and walks down the street.
