and Steve make a bet: if Steve beats Buddy in the WinterFest speedskating race, then Buddy removes the lights, and if Buddy beats Steve, Steve pays for the car. Buddy wins, causing Steve to yell at Buddy for being a nobody, since his house is still not visible from space. Hurt, Buddy compensates by buying a huge amount of programmable LED lights, which he pays for by hocking Tia's expensive heirloom vase, and Tia and the girls depart. Having had enough, Steve buys various fireworks including The Atomic Warlord, a large, illegal, military-grade rocket from a gangster and tries to destroy the Hall house. The rocket misfires, setting the town Christmas tree on fire, and Steve's family leaves, but not before Kelly scolds Steve for ignoring his children to focus on Buddy. Steve discovers Buddy has been stealing the former’s power for the latter’s lights. However, after seeing Buddy taking down his lights, a remorseful Steve forgives Buddy. The two forget their rivalry and build a winter wonderland with all of Buddy's lights. They lure Tia, Kelly, and the kids home and all sit down to a nice meal made by both Steve and Buddy. Soon, the whole town arrives at Buddy’s house to help put Buddy's lights back up in time for a story about them on MTV. They do not work, and everyone sings carols and uses their cell phones as flashlights. As they sing, Steve accepts Buddy’s offer to be his friend, and Carter notices that the lights did not work because one of the plugs is not plugged in properly. He tightly plugs it in, causing the lights to shine brightly through the night. SuChin Pak, doing the MTV report, gets confirmation from MyEarth that the house is indeed visible from space, and the crowd celebrates.
