Munk vs Machine / Shack Magic The Chipmunks and Chipettes enroll in a dodgeball tournament, but are upset to see that Bocarter's team is utilizing a number of devices to boost their own gameplay, including specialized intercepting goggles, and a mechanical, dodgeball-launching android. Angry about the opposing team's unfair advantages, Coach Dopkins otherwise finds nothing in the rule book that signifies that any of their tactics are illegal, and are permitted to play. In the meantime, Theodore discovers a pair of abandoned socks that he turns into puppets, but during a game, one of the puppets is knocked off of Theodore's hand, causing him to fly into a fit of rage as he pummels the opposing team with dodgeballs, and doesn't remember a thing after he calms down. Alvin and the others decide to use their to their advantage, and when Kevin weasels his way out of the team, they bring in Theodore as his replacement, goading the other team into knocking the puppet off of his hand, prompting him to fly into another fit of rage, once again pummeling the opposing team with balls, and winning the tournament for them. Theodore discovers a seemingly magical shack in the woods that bears all kinds of fancy gifts, such as gaming consoles, electronic devices, and other similar items that would be any kid's wish come true. Each and every day, whenever he, Alvin, Simon, Kevin, and Cheesy return to the shack, more and more of these good appear out of nowhere, though Simon is certain there's a more logical explanation for all of this, and enlists the help of Officer Dangus to get to the bottom of this. After witnessing the supposed magic for himself, Dangus is convinced that the shack isn't just magical, but also a portal being used by Santa Claus to store Christmas gifts as he travels. After gathering some of the items and bringing them down to the station for evidence, he and boys learn that the shack was being used as a hide-away by a pair of thieves who had been committing a string of robberies all throughout town, and were scared into turning themselves in, after discovering the very vague thank-you notes left behind by the boys they interpreted as threats from rival thugs who were out to get them.
