Answer:
What goes up and down stairs without moving?
I have a small hill with seven holes.
Though desert men once called me God today men call me mad. For I wag my tail when I am angry. And growl when I am glad.
I am orange and sound like a parrot.
The more you take away from me, the bigger I shall get. What am I?
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.
