Adventure Time Season 9 Episode 11 - Ketchup Episode Title:Ketchup.Episode Description:Marceline is unexpectedly visited by BMO, who is asked to download a USB drive. While they wait, BMO tells the story of it, Finn and Jake traveling the seas; the mostly-inaccurate story involves a cat named Ted and a blue jay (voiced by J. G. Quintel). Marcy then tells the story of "Lollipop Girl" and "Rock Star Girl" and their encounter with a "Blue Tranch", which resulted in "Weekend Island" being taken over by potatoes. When the USB drive downloads, it reveals pictures of young Marcy with her mother. She pretends not to know them, and asks BMO to tell their story: a tale about "the Child and the Moon Girl", for which Marcy is grateful.
