After exiting the ruins, you decided to explore the unfamiliar area filled with snow.

You hear footsteps behind you, but you never looked back.

Then, you were near an incredibly large fence... so large that anything can pass through...

You suddenly hear a voice behind you. And the voice is really intimidating, but you swear you can hear small giggles, as if this was a prank.

Sans: "Human... Dont you know how to greet a new pal...? Turn around and shake my hand."
