Answer:
I keep things green and keep kids happy during summer time.
If you drop me, I'm sure to crack. Give me a smile and I'll always smile back. What am I?
I am commonly ate before I'm born and after I'm dead.

When I live I cry if you don't kill me I'll die.
What do you purposefully put lots of in and on your body, but run away from when you encounter it outside?
