Meanwhile, LSP and Marceline take a stolen car and make their getaway, they suddenly ram right into Breakfast Princess, just as she runs right in their path. LSP thinks they killed her, but Marceline can hear her moaning, meaning that she was only dazed from the hit. Marceline decides to kidnap her and locks her in the trunk of the car.

After driving out into the desert, LSP and Marceline decide to don masks to disguise themselves, but Breakfast Princess easily sees through LSP's mask. As Marceline forces her out of the car, LSP gives Breakfast Princess a shovel and they order her to build a giant sandcastle. And while she beings digging, both Marceline and LSP decide to strand her there. When LSP and Marceline drive away, Breakfast Princess stops digging and walks away, what happened to her next is unknown as she doesn't know which way the Breakfast Kingdom is.
