Merry Christmas from the tallest, most festive home in the world! Andy and Terry are preparing for the holidays, and they have added thirteen new levels just in time for the season. Discover the wishing well, try to win big on a TV quiz show hosted by a robot, or order a snack from the amazing mind-reading sandwich-making machine that knows exactly what you are craving. But the night before Christmas is quickly turning into a total disaster. The boys have not written their letters to Santa or hung their stockings, and now they are at war with an incredibly angry snowman. To make matters infinitely worse, Santa Claus has crash-landed his sleigh right into their branches and accidentally fallen straight into their new cloning machine. With dozens of identical Santas running loose, the duo must scramble to figure out who the real one is, save the holiday, and finish their book by morning.
