Answer:
My head bobs lazily in the sun. You think I'm cute for my face is yellow my hair is white and my body is green.
I am seen in the water. If seen in the sky I am in the rainbow a jay's feather and lapis lazuli.
I go in hard come out soft. Blow me hard and I’ll make a pop.
Some people avoid me some people count me some people just consume me
My first is in fish but no in snail. My second is in rabbit but not in tail. My third is in up but not in down. My fourth is in tiara but not in crown. My fifth is in tree you plainly see. My whole a food for you and me.
No matter how little or how much you use me, you change me every month.
