The Hatch down to a mysterious forest was rumoured to be filled with mystical creatures, as you open the hatch alone with yourself, you jump in with absolutely no exit, but luckily, you gave yourself a rope attached to a wooden, thick stick in the floor piercing outside it, In the forest, you see The Lost Soul.

Lost Soul: "Oh. Hey! I have a task for you, mind re-attaching this skeleton? Here's the right arm I just got, please attach it."

You attach it, seems like the rumors were real.
