On Christmas, Rick sends Morty inside the body of a homeless man to save his life (a parody of Fantastic Voyage). Inside the man's body is a microscopic enclosure called Anatomy Park (a parody of Jurassic Park), which houses various deadly diseases that escape their enclosures. Back at the family home, Jerry's parents visit, and the family attempts to bond without electronic devices.
Post-credit scene: Rick contacts Annie and her other new associates inside his new patient's body and as they talk about his "Pirates of the Pancreas" ride (much to Rick's dislike, since he is sensitive about his ride because it's his idea). Rick hangs up on them only to proceed with a rant and insults.
