- Sequel in Another Medium: This is the second Adventure Time comic to take place after the end of the series, only this time focusing on Marceline and Simon.
- Spoiled by the Merchandise: Amazon listed a trade paperback version of the miniseries in their page containing major spoilers for the miniseries. Not only that, but BOOM!'s May 2019 solicitation catalogue also spoils the same thing: Finn, Jake, Marceline and Simon will travel through the multiverse to unfuse and rescue Betty from GOLB.
- Written by Cast Member: Written by Olivia Olson, the voice of Marceline in the show.
