You correctly judged the distance, and the rock is about to land directly on the weasels. The evil creatures jump away towards a nearby tree, and the map lands gently on the ground behind you. You'd like to just grab the map and be on your way, but you know if you turn your back they will jump on you and eat your brains. What's worse, the very second you are ready to fire your pistol at one of them, they let go of the branches and fall to the ground, then run back up the tree. How will you ever be able to hit them if they keep letting go like that? Where should you aim?
