In their second year at Greendale, Abed had a mental episode due to his mother telling him she wouldn't be visiting him for Christmas. 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 and Professor Ian Duncan tried to help him deal with his delusion by staging an intervention. They worked through his problems by indulging his fantasy of traveling to "Planet Abed" and finding the true meaning of Christmas. After they discover the source of his trauma, the study group protects him from Duncan who plans on exploiting his pain. While defending him they sing "That's What Christmas Is For".
