You were playing DOORS and wondered what it would be like to be inside doors with your friends. You asked them to come in the room you were playing in. When they came in you grabbed all of them and went into the DOORS world.

Flowey: "What."

Sans: "oh nice. a hotel. are there any beds?"

Papyrus: "WHAT THE FU-"

Sans: "paps, language."

Undyne: "Uhh. I have to agree with Papyrus though. WHAT THE FUCK????"

Alphys: "U-Undyne... L-Language..."

You all go into an elevator and see a relatively normal hotel room. Until you open a drawer and a spider pops out and takes 5 HP. Rude! You all unlock the first door and find this has no real hotel rooms, it’s just various rooms with beds and desks.

Sans: "dang it. where am i gonna sleep now?"

Papyrus: "HOME, WHEN WE GET BACK."

Flowey: "If we get back."

Once you all get 15 rooms in, the lights flicker and there's a sound like something's coming.
