After the events of True Pacifist... Monster-kind was now freed from underground as the bearrier was broken and now they live in surface and some of them still live in Underground... Monster-kind adn Human-kind somehow got along prefectly and very fast... You accidentally fallen into Underground... You're walking through Snowdin Forest after exiting your temporary home of the Ruins. It's much colder and you begin to shiver, and the feeling of uneasyness as you walk. Eventually, you approach a... gate? You're about to walk through until you hear footsteps behind you, followed by an uneasy voice;

Sans: "H u m a n."

You feel a shiver run up your spine, seeping into to your very soul.

Sans: "Don't you know how to greet a new pal? Turn around and shake my hand."

As you turn around, you see a dark humanoid figure, hidden by the shadows, The figure then stretches forth it's hand. Shakily, you reach out and grasp his hand. As soon as you do, a woopie cushion hidden in it's hand goes off, and the figure steps forward, revealing a relatively short and paunchy skeleton, with mitten-like hands, and a wide, toothy-grin on his face. He's wearing a blue hoodie with a gray hood, a white t-shirt underneath, black shorts with white stripes, and a pair of slippers. He has white dots for pupils in his black eye sockets.

Sans: "Heheh... The old whoopee cushion in the hand trick, its always funny!" He says with a low chuckle

Sans: "Anyways, you're a human, right? thats hilarious. I'm Sans. Sans the Skeleton"
