small food/mob update (crows n corn)

this update would add crows that peck and steal your crops and a new food, which would be corn. carved pumpkins or Jack o lanterns would scare the crows away, and villages would have scarecrows made of hay blocks on a fence and a carved pumpkin on top. this could also add a new soup, corn chowder, made from a bowl and 6 corn. you could also maybe put corn seeds in a furnace to make popcorn. in terms of hunger the corn would be like pumpkin pie, in that it gives more hunger at the cost of less saturation.
