He starts drilling his body out and Jake screams in the process, the city now starts to rumble and the large pillar of sand collapses causing an avalanche of sand towards them. Jake manages to free himself from the quicksand and Marceline grabs them both before the sand avalanche hits them.

Marceline said that he demolished half the city, Finn then adds that he sealed their exit, their only exit. Jake apologized and says that he will dig their way out of there, Finn and Marceline said no or he will bury them alive. Finn pulls out his Holo-pendant and calls PB for help, but there is no signal.

After he left, Jake asks how hungry she is, Marceline replied with a hiss, Jake is frightened and apologized, then he quickly said "Please don't eat my blood!" Marceline said that she does not want to hurt Jake and lets him know that things will go crazy if she is hungry, and she will go on feral mode, Jake has no response, but Marceline said that she will tie herself up so that he wouldn't be scared, he agrees then he did so.

He discovered that the people in the cave are not actually sand people, but people turned into sand by the red light. He passed it and crawls into a hole. The scene cuts back to Jake and said that Marceline is going nuts. Marceline starts to threaten Jake that she can smell his insides, Jake screams and the scene cuts to Finn. Finn is still crawling in the hole, in the end of the hole, he found a turtle like creature shining red light to the gem. Finn asked if he can have the ruby, but the creature said that it's an emerald, they had a little chat and the creature then walks out into the shadows as Finn moves the gem.

The scene returns to Jake who has covered Marceline with sand except her head, Marceline said that she can't control herself much longer then apologizes as she laughs evily. Jake quickly thinks of a plan, but is too hungry to do so, but he intends to cook Marceline before she eats him. After surrounding Marceline with lava, Finn arrives with the gem looking exhausted, Jake said that it isn't a ruby, and that it is an emerald, Finn denies it, but later on, Jake said that Finn might be a little colorblind and notice that the gem is indeed an emerald. Finn suddenly notices that Marceline is gone, making Jake panic and pushed Finn into a hole. Suddenly, a giant worm bursts through the ceiling before Marceline could eat Jake, Princess Bubblegum arrives in the worm's mouth controlling it, Jake warns her that Marceline has gone rabid, but it's too late, Marceline grabs PB and bit her hair, draining her. Marceline returns to normal, and said that they should go.
