In the study group's second year at Greendale, Abed had a mental breakdown right before Winter break. He imagined the world had become stop motion animated just like the shows he and his mother would watch over the holidays. The study group stages an intervention alongside Dr. Ian Duncan and convince Abed to undergo hypnotherapy. Abed imagines they are all transported to the Christmas world called "Planet Abed" and that his friends have joined him on his journey to the North Pole in Christmas toy forms. Jeff is unable to take the session seriously and his sarcasm caused his character to be eaten by Humbugs. To commemorate his death, Annie offered to sing "Jeff-in-the-box's Christmas exit song". It was first heard in the Season Two episode "Abed's Uncontrollable Christmas".
