Mob enhancements

With 1.18 upgrading generation and 1.19 upgrading biomes mobs feel left in the dust. Most of the passive mobs are only useful for there drop. This is why i think mobs should gain uses outside of drops. For example pigs could hunt for mushrooms or truffles if added . This may also mean adding more mobs to make current ones feel more alove and realstic. For example birds, birds could have a similar mechanism to tropical fish so theres dozens with one egg. So much could be done to enchance mobs which is why i think this would make minecraft a more intresting game
