Welcome to the world of Sonictale! Here you'll be a brown-haired boy wearing Frisk's t-shirt, but just in case, write your name. Remember, your actions will have consequences in the future.

Enter the name of the fallen human:

Once you enter the name, you fall underground, but it's different; it has a dark cave theme. You keep walking and you encounter a robot Chao.

OmoChao: "Hello friend, if it's what it seems, can I talk? Are you new to the Underground?"
