Ketchup

"Ketchup" is the name of the eleventh episode of the ninth season of the American animated television series Adventure Time. The episode was written and storyboarded by Seo Kim and Somvilay Xayaphone, from a story by lead writer Kent Osborne, Jack Pendarvis, Julia Pott, Patrick McHale, Ashly Burch, and series showrunner Adam Muto. It originally aired on Cartoon Network on July 18, 2017 and guest stars J. G. Quintel as a blue jay. The series follows the adventures of Finn (voiced by Jeremy Shada), a human boy, and his best friend and adoptive brother Jake (voiced by John DiMaggio), a dog with magical powers to change shape and grow and shrink at will. In this episode, Marceline is unexpectedly visited by BMO who is asked to download a USB drive. While they wait, the two tell each other stories, leading to BMO telling Marceline the story of "the Child and the Moon Girl", based on Marceline and her mother. Plot Marceline (voiced by Olivia Olson) is unexpectedly visited by BMO (voiced by Niki Yang), who believes that vampires are still threatening Marceline's life. Marceline assures the robot that the vampire threat passed months ago, and asks BMO to download the contents of an old USB drive. While they wait for BMO to secure the contents, the two decide to tell each other stories. BMO goes first, describing how it, Finn and Jake recently traveled the seas. However, the story gets highly exaggerated and surreal, involving a cat named Ted and a blue jay (voiced by J. G. Quintel). Marceline then tells the story of "Lollipop Girl" and "Rock Star Girl" and their encounter with a "Blue Tranch" that resulted in "Weekend Island" getting taken over by a potato curse.
