You are drinking hot chocolate in your room, but suddenly a loud noise comes out of the kitchen. What is going to happend next? (Pic not mine and unlike the picture, there is Fell sans, Swapfel sans(the red one) and Cross Sans. You will see that the sanses aren't too hostile, because that's the way I see them and what would be the fun if they kill you at first sight?)
