Tom appreciates Jerry's warning and the mouse runs back to his hole. Jerry uses the cane to fish a mousetrap that he had earlier planted in the bowl. He dips his cane into the bowl, and a loud snap is heard. A delighted Jerry licks his cane, but then quickly reacts to prevent Tom from drinking from his bowl of milk. Tom hands Jerry a candy cane, his Christmas present. Slowly, Jerry regains consciousness, but is wary of the cat. Fearing for Jerry's life, he brings the frozen mouse indoors and warms him up by the fire. He first props open the slot to allow Jerry back in and, when the mouse does not reappear, ventures anxiously outside to find Jerry, frozen. He is unable to settle himself heavenly choirs sing carols, pricking Tom's conscience with the message of Christmas peace and goodwill.
While Jerry trudges up and down in the heavy snow in a vain attempt to warm himself, Tom fluffs up his cushion and prepares to sleep. Tom angrily barricades the slot so that Jerry cannot get back into the house. As Tom opens the lid of the letterbox to see where Jerry has gone, Jerry hurls a snowball at his face. The mouse darts through the letterbox slot into the outdoors. Tom blushes, and while his back is turned, Jerry kicks him in the rear. Tom chases Jerry once again, but Jerry holds out a piece of mistletoe in front of him and persuades an embarrassed Tom to kiss him. Jerry jumps out and holds it up in victory like a boxing referee. Opening up the box, Tom is punched by the boxing glove stuck on Jack's head and is knocked out. Tom, now arming himself with a boxing glove of his own, follows him and spots him jumping into a Jack-in-the-box. Jerry hides inside a boxing glove and boxes the puzzled cat in the face before running off behind the Christmas tree. He quickly runs through the tunnel, pursued by Tom, who knocks the tunnel over. However, the train enters a model of a tunnel, and Jerry, sitting on top of the train, hits his head, knocking him onto the track.
Jerry is sitting on top of the caboose, waving cheekily at Tom and pulling faces. A toy train passes by, with many Passenger Cars. Tom chases Jerry, but is stopped by the barrier of a miniature level crossing. Jerry hides among some toy soldiers, but Tom spots him, and just as he is about to crush Jerry with his paw, the mouse runs off. Tom, obviously not fooled by this, grabs Jerry and is promptly electrocuted. Jerry hides among the myriad of toys (even firing a trick cannon's cork at Tom) and hides inside a Christmas fairy light, causing him to glow.
Tom snarls and just before he can eat Jerry, the quick-thinking mouse grabs a nearby "Do Not Open 'Til Xmas" sticker and instantly places it on Tom's mouth. Jerry jumps up and down on the grey fur, not realizing that he is jumping on, in fact, Tom, who has woken up. Jerry continues jumping on the soft toy, but bounces too hard and lands on what he thinks is another soft toy. Jerry quickly heads for the Christmas presents, jumping merrily around the tree, licking candy canes, and jumping onto a plush toy lion that squeaks. Jerry emerges from his hole avoiding a Christmas-themed mousetrap (already baited with a piece of cheese wrapped in a red ribbon) placed by his hole. In a house on the night before Christmas, nothing was stirring, not even a mouse.or so it was at first.
