In this one-hour musical episode, Linda is determined to host a party at the restaurant, in an effort to spread a little extra cheer around the neighborhood. But when she realizes that her prized ornaments have been stolen, she quickly begins questioning all guests, including Marshmallow's (guest voice David Herman) friend - Art the Artist (guest voice Adam Driver). However, the kids have their own theory, attributing the robbery to the anti-Santa - The Bleaken.
