Lets chat about Rams and Billy goats!

Hello! I would like to introduce my idea for these new unique mobs. Rams; Rams are a unique brown white and black curly horned animal that live in rocky/stone mountains just below the snow level. you might think they are too similar to Goats to add but trust me they aren’t. the way they would works is not only do they head but you but they also head but trees and each other in combat, just like real life! They do not drop horns and they do 4 hearts for critical damage and 2 for base damage. As the babies grow up the horns curl in stages just like real life, stage one (birth) the horns are little nubs, stage two (Child) they are curled but not fully, and stage three (adult) the horns are fully curled and as the rams grow and the horns do too the horns do more and more starting at half a heart, then a full heart, then 2 hearts or 4 based on critical damage value. That is all for rams, now it’s time for Billy goats! Billy Goats/Village goats; These goats are simple animals that could be very useful when need be! They can be milked for goats milk unlike mountain goats and rams, this milk would have special properties and have trade value in butchers. instead of potion effects being taken away this milk would just heal two hearts a bucket/bottle. These goats can also pull around apple wagons! You would craft these with 5 wood one apple and two lead and these would be handy to put small items in but not blocks, these billy goats would only be found in villages. Thats all Thanks!
