In Beautopia, Finn, Jake, and Susan Strong break down a door during high tide that reveals an arcade. Jake doesn't seem to like the place, but Finn says that they are investigating early human culture, so they'll probably find all kind of cursed artifacts. Jake starts to get a little bit excited, since it has been a while since he has received a good hex.

While walking through the arcade, Jake states that someone could get cursed and that he hopes it's him. Susan comes across an old merry-go-round buried in sand and they pull out. Finn says he thinks that it's the bones of a prehistoric horse that was covered in feathers and used its poles to sting people who tried to steal its honey. Jake doesn't seem to believe Finn and states that he said there would be hexes. He is unable to finish his sentence when he trips over a dinosaur plush buried in some more sand.

Jake sits up and thinks that the dino plush is a "demon." He pulls it out more and sees that it is only a dino plush and refers to it as a little cutie. The ground begins to shake and Jake thinks that this is because the dino plush is cursed. Finn thinks there is an "Ooo-quake" and with that, he and Susan take Jake with them and run outside.

They come outside to see a massive animal-like robot digging its way to the surface right next to Beautopia. Finn, Jake and Susan stand outside it to see what appears to be the eye of the machine open to reveal a walkway down to where they are. The fog clears and Tiffany is standing on the walkway with a bionic arm.

Finn appears happy to see him and thought that the worm queen ate him. Tiffany then tells the gang to come with him and that he'll explain almost everything. Finn, Jake and Susan shrug to each other and follow Tiffany inside. The door opens for them and a robotic voice welcomes them. The Walkway continues and winds around a corner. There are flowers and various shapes floating and growing around them.
