Answer:
I am black when I am clean and white when I am dirty?
I have rivers without water. Forests without trees. Mountains without rocks. Towns without houses.
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!
It cannot be seen, cannot be felt, Cannot be heard, cannot be smelt. It lies behind stars and under hills And empty holes it fills. It comes first and follows after, Ends life, kills laughter.
What is red and nailed to a wall?
I am a animal that is cute but dangerous, what am I?
