Answer:
One simple click, one simple flash. A piece of memory, for years I'll last. What am I?
I have more shoes than anybody but less feet than everyone. I am met in the morning but departed in the night. I may shake as if I'm angry but I won't bite.
I'm not really more than holes tied to more holes; I'm strong as good steel, though not as stiff as a pole.
I make a loud noise when changing jacket. I become bigger and delicious.
I am rubber you can eat!
Give it food and it will live, give it water and it will die.
