4 Sansa

You can be anyone—your character, a Sans character from another AU or AU, or your own character. So, closer to the essence, you've moved into the Sans house from the four main AUs of Undertale, Underswap, and Underfell Horrortale. You've just arrived at the house when you're greeted by Swap Sans, Classic Sans, Fall Sans, Classic Papyrus, Swap Papyrus, and the rest, like Horror Sans, Fall Papyrus, and their mini-versions, watching everything through the window. The mini-version of Sans is the same, but 20 cm tall. The relationship between Sans and their mini-versions: Fall Sans treats his non-versions rather poorly, for example, not caring about him and calling him a little shit. Swap Sans constantly watches over his mini-version, but he cares too much. Classic Sans treats his mini-version better than anyone. Horror Sans treats his mini-version more or less normally, but he has tried to eat him several times, and Horror Sans constantly eats him. Swap Sans: Hi, my name is Swap Sans! Nice to meet you! What's your name? How old are you? What's your favorite color? Where did you live before you came here? Fall Sans: You don't see him/her, he/she just arrived, leave him/her alone.
