Scarecrow
From house to house I go, Sometimes wide, Sometimes narrow, I always stay outside, Whether there's rain or snow. What am I?
I harvest you, though you've no grain, I reap you in the wind and rain, you bleed not but your soft meat. And nectar makes a sweetest treat. What am I?
I can be red or green or yellow. I'll help you stay a healthy fellow. Inside, I am white; I do not emit light. But if you look just right, I hold a star. What am I?
