Answer:
What bird is always unhappy?
I am a bird but I cannot fly. I'm the fastest runner of all birds. What am I?
My first is in ocean but never in sea. My second's in wasp but never in bee. My third is in glider and also in flight. My whole is a creature that comes out at night.
What is it that has a power socket on one end and a corkscrew on the other?
Face with a tree, skin like the sea. A great beast I am. Yet vermin frightens me.
You use it between your head and your toes, the more it works the thinner it grows.
