A door appears, which you walk through. You end up in a movie theater, and the abridged history of Elliot’s time in your pocket is being played.

You go back through the door, and back into Hyperspace. “That was boring,” you think. You take the door, and put it in your pocket. You figure Hyperspace makes your pockets bigger on the inside. Elliot is out of MP.

You can:
Use the door as a surfboard
Go try to find a flower
Throw your shoe at the door.
