-- Nancy may walk into the residence tent and hear an ominous sound coming from her bunk. (But it also may not happen to you; it might be random.)
Yikes! What do we do about this? Well, in real life I'd just back slowly out of the room, but in this game you have the tools you need to take the snake into custody yourself. (But please don't try this at home. Really.)
For some reason, Nancy has a long Y-shaped stick by her bed, as well as a large plastic trash can with a lockable lid. Right, everyday stuff.
Grab the stick, pull the trash can over to the bed, and then use the stick on the snake to put it in the trash can.
