Elsewhere the Lich-possessed Snail crawls into a nearby bag and when it comes out the Snail is no longer possessed, but the Lich is free and uses the bag to suck his surroundings.
Back at the Tree Fort, Finn and Jake are practicing cool phrases to say during battle when a loud sound causes them to look outside to find the Lich sucking Tree Trunks into his bag and heading to the Candy Kingdom. The duo dons their anti-mind control jewelry and head into battle. They find the Lich sucking a swath through the planet into his bag. The Lich informs them that he plans to suck the entire planet into his bag then throw it into the sun. To battle him, Finn and Jake combine into "Jake Suit" mode, although the Lich just brushes off their attacks and informs them that them that he had already sucked up the Candy Kingdom. Then he suck Finn and Jake into the bag and they land in a desert and meet Desert Princess, who informs them that she was sucked up by the Lich also and gives them an example of her powers to control sand by making a Sand Finn clone. Finn tries to think of a way out but Desert Princess remarks they may be trapped there forever.
