Sandy informs SpongeBob that she is preparing for the holiday season, and explains customary Christmas traditions to him. While heading to Sandy's treedome for a surprise visit, SpongeBob SquarePants is horrified to see her electrifying the tree with Christmas lights, perceiving it as a house-fire. Patchy explains that they did not always celebrate Christmas in Bikini Bottom, and decides to show how they were introduced to it.
