You clamber up onto the ledge and see the small bright pig disappearing down a long low crawlway. You try to follow her but you are too big to fit into the tunnel she went thru. You search around and find a ledge of sorts that might lead to the top. You begin inching your way along the dripping, cold, slimy surface of the well wall. You pass a small tunnel that you could possibly fit thru. Further up the wall is a larger opening. The projecting ledge gets wider and appears to go to the top. 

    wiggle into the small hole
    climb up and walk thru the higher hole
    climb to the top where you will see....

Or can can try escaping by teleporting into the Maze:
    upward roundabout cross-ways or forwards
