Production
A couch gag with The Simpsons climbing up an ice mountain and Maggie turning them into ice is released as a promo image for the episode before appearing on the Season 28 finale, Dogtown. The episode was originally going to use that couch gag, but according to Al Jean's twitter, it is too short, so The Game of Life couch gag from season 25's "Pay Pal" is reused.
