"Ohh... agh... what a fall... huh? Where am I?"

You say to yourself after falling from such a great height and somehow surviving...? You get up and see thay you're inside some mountain thingy... someone then pops up behind you, jumpscaring you

"Oh, hey fellow survivor! Welcome to hell! No, I'm just kidding, this isn't hell, obviously. Anyway, see those smiling dudes over there? Yeah? Don't get near 'em. I'll explain the rest later"
