Hippopotamuses

Hi Mojang, I would like to suggest that river biomes in/near savanna’s could have a chance to spawn hippos. These mobs would be neutral, and would not go after you, but attack you if you get into the river. They could be about as strong as the hoglin, and would follow you on land ONLY if you hurt them. If you got in the water then in land they would not chase. They would be able to be breed using grass, and the baby’s would be passive, running when hit.
