When Stan, Dipper, Mabel and Soos find themselves falling into a bottomless pit, they each decide to tell a different story to pass the time.

When Dipper discovers a hidden room inside the Mystery Shack, he is happy to claim it as his own space, but there is one problem - Mabel wants the room too. The duo compete to win the room with a contest that gets even trickier when they learn the room's carpet has electric body swapping properties.
