minecraft earth buttercupcow in minecraft

I would like to suggest that their could be a new biome like the mushroom island but for buttercup cows that can be and island and has big buttercup structers made out of clay or if they want to add new flower blocks (like a stem block). And the normal buttercup flowers would spawn on the grass. They could even do a new kind of grass and if you put a buttercup flower on the new grass block and bonemeal it, it would spawn a flower (buttercup) just like the mushrooms.
