Answer:
You can build or destroy. Let creativity soar but be careful at night.
I am the key that is the hardest to turn
I am black and white. I have strings I have keys. I make sound without my lips. I make dough with no flour
Born in the ocean and white as snow. When I fall back to water I disappear without a trace.
I always murmur but never talk. Always run but never walk. I have a bed but never sleep, have a mouth but never speak. What am I?
A leathery snake, with a stinging bite. I'll stay coiled up, unless I must fight.
