A house of wood in a hidden place. Built without nails or glue. High above the earthen ground. It holds pale gems of blue.
I have an eye but cannot see, You'll head inside when you see me.
Glittering points that downward thrust. Sparkling spears that never rust.
Long and think, red within, with a nail at the end.
White fat and fluffy, May even look like a puppy. Seems heavy but is light, Floats about without a worry, But if it turns dark you have to hurry!
