Answer:
I am the type of room you cannot enter or leave. Raise from the ground below I could be poisonous or a delicious treat.
I carry you down a gentle stream.
My teeth are sharp my back is straight to cut things up it is my fate.
I have a neck and no head, two arms but no hands. I'm with you to school, I'm with you to work. What am I?
I can generate fear and some say I come out of your ears. I am as quiet as a mouse but not welcomed in the house.
Though not a plant, has leaves. Though not a beast, has spine. Though many wouldn't need this thing, It's more valuable than wine.
