Ideas for mud

I think it would be cool if if you go in mud then the warden can't smell you. Maybe the mud can give a effect called smelly or something so the warden can't smell you and maybe other mobs can lose you more quickly if you move out of sight. I think it would be adorable if pigs rolled in mud, and could maybe dig things up to make pig more useful and not just a food source. I think mud slides would be cool I don't really know what it could do or how it would happen but I think it could be cool. Mud has a lot of potential and I can't wait to see where it goes. Thank you for reading my Idea. (:
