Answer:
First you see me in the grass dressed in yellow gay; next I am in dainty white, then I fly away. What am I?
I tell people to be careful when handling boxes.
I wear a red robe with staff in hand and a stone in my throat.
I am alive without breath and cold as death. I am never thirsty but always drinking.
I am a precious stone as clear as diamond. Seek me out while the sun's near the horizon. Though you can walk on water with my power try to keep me and I'll vanish in an hour.
Though not a plant, has leaves. Though not a beast, has spine. Though many wouldn't need this thing, It's more valuable than wine.
