Finn and Jake try to find a way to use all the sand that was in the bag, which is now spread across the Land of Ooo. Ice King kidnaps Desert Princess who after being freed by Finn and Jake, uses her powers to create sand clones of herself. The clones then jump into the crater made by the Mushroom War, creating a new Desert Kingdom for Desert Princess to rule. Princess Bubblegum asks Water Princess to make a lake in the new kingdom. Everyone has a party on Desert Princess's new lake, concluding The Lich Story for now.
In a flashback, Marceline is shown 1000 years before the events of the comics. It show her inside the cave while the Mushroom War is occurring outside. She eventually discovers the Bag of Holding.
In "The Ultimate Party Dip," written by Chris Eliopoulos, Party Pat heads out to get ingredients to make the ultimate party dip. The ingredients are the meanest prickle pear, couple strips from a bacon tree, hot lava pear, cave people salt rocks, and slimy underwater jelly nerd. Party Pat finished the dip and heads back home but forgot to bring chips. Pat then says the bears can use their paws and the party continues.
Flame Princess and Choose Goose make their first comic book appearances in brief cameos at the end part. However, Flame Princess was mentioned by Finn in issue 3 while searching for his friends in the Bag of Holding.
In the collected edition of the comic book, Marceline's coloring in the flashback is changed to the more demon-like look seen in "I Remember You."
