I am always in front of you, but you will never see me. What am I?
I'm blue at day and black at night. I do contain some creatures born and died. What am I?
I dig out tiny caves and store gold and silver in them. I also build bridges of silver and make crowns of gold. Sooner or later everybody needs my help yet many people are afraid to let me help them.
When set loose I fly away. Never so cursed as when I go astray.
