Finn, Jake, and Desert Princess search for a way out of the Bag of Holding. Along the way, they meet up with Ice King, who decides to have a sand-and-ice picnic with Desert Princess. Meanwhile, the Lich continues sucking up places and people in Ooo, including Marceline, who lands on an island inside the bag with Princess Bubblegum. Lumpy Space Princess also gets sucked in and lands on Jake.
Finn and Jake (with Desert Princess, Ice King and Lumpy Space Princess in tow) drill into the ground and find the fabric of the bag at the bottom. They attempt to escape by punching though it, and get absorbed by it. As Marceline and Princess Bubblegum meet up with the others, Lumpy Space Princess declares that she believes Finn and Jake are dead.
