Chocolate cow mob

Dear Minecraft Team, My name is Noah and I have an idea for a new Minecraft mob called the Chocolate Cow. It would look like a normal Minecraft cow, except it would be different shades of chocolate brown with lighter patches. Chocolate Cows could be quite rare and live in certain biomes. If you milk one with a bucket, you could get Chocolate Milk instead of normal milk. Maybe drinking Chocolate Milk could give the player a small positive effect. You could also feed a Chocolate Cow cocoa beans. Perhaps cocoa beans could be how you breed them, or there could be a very small chance that feeding cocoa beans to a normal cow turns it into a Chocolate Cow. I hope you like my idea!
