Answer:
I have a little pool with two layers of wall around it. One white and soft and the other dark and hard. Amidst a light brown grassy lawn with an outline of a green grass.
I fly away as soon as you set me loose. People around you may slowly move away once they sense my presence.
Iām grown from darkness but shine with a pale light. Very round I am and always a lady's delight.
I am a vegetable that bugs stay away from
When I live I cry if you don't kill me I'll die.
I run through hills. I veer around mountains. I leap over rivers. And crawl through the forests. Step out your door to find me.
