I know this is an old subject (I'm slow), but I would appreciate a little help 
in this trivial matter from those who know.

I'm about to give up on Uninvited.  I can't get the little guy who runs 
around.  I can't get through the door in the den.  I don't know what to do 
with the animals I cage.  I don't know how to get by the group of zombies in 
the maze.  Etc.  I've gotten hints on things like the little guy who runs 
around (he's hungry) but I've tried everything (except the correct process) 
and I can't trap him.  If getting his key will lead me to solving the further 
problems, I would really appreciate it if someone could tell me the answer to 
his puzzle (or some other progress-stopper).

Thank You,
Hunter Gordon
