Animal is in charge of tinsel, Sweetums hangs the lights, Sam Eagle strategically places the mistletoe - everything is in order. Or so it seems. Meanwhile, Miss Piggy offers relationship advice to Fozzie, which forces her to reevaluate her relationship with Kermit. Yolanda rigs the Secret Santa gift exchange, and Echosmith performs at the crew's Christmas party.
