Oh, it's a gigantic (10") cave troll! You pull a lever on it's back and WHAM! It's hammer swings down and it lets out this horrifying roar and it's jaws open up! My three year old is terrified of it! LOL It has another lever on it's back for the other arm and you put the spike in it and it does the same thing...roars with it's mouth open, just like in the movie...it looks just like it could impale Frodo any minute.
