Trivia

 * This episode serves as the series finale of Doraemon in the Big City. It is a one-hour episode.
 * The climax between Noby and his mom, who is Tamzilla, is similar to that of the Pixar film Turning Red.
 * This episode shows Tam-zilla's villainous child abuse on Noby. She is the most extremely unlikable character in this episode.
 * Cuphead, Mugman, and Ms. Chalice (in the style of Cuphead Show!) were originally going to appear in the episode, but the Disney executives reject it due to copyright issues with Netflix. So they were replaced with Pain and Panic from Hercules. Despite this, Casey Nicholaw, one of the producers of the show wanted to put Cuphead, Mugman and Ms. Chalice in the episode because he thought they could be comic reliefs for Noby, Doraemon and Sue, but the Disney executives rejected this as well.
 * Despite this, Cuphead, Mugman and Ms. Chalice appeared in the storyboard version of the episode where they were helping out Noby, Doraemon and Sue in their ultimate battle, then they were cheering Noby on the battle.
