What if we added hogs?

I think maybe we could add hogs to the game as a new passive mob! They could be found in herds of pigs in the jungle. They would also be a new form of transportation(though not a good one), after taming it with potatoes it could search for and dig up truffles most likely found in forests, to be added to natural food items(such as carrots, chicken, and salmon) to give the item an increase in the amount of saturation and hunger added. If given farmed items the hog can actively search and guaranteed dig up the item. If fed the new food item the glistening potato (crafted with 4 glowstone in the corners, 4 golden nuggets in a plus shape, and a potato in the center) then the hog will then become an adjacent to the copper golem becoming able to return items to the player who tamed it or a chest/barrel to brcome a new farming opportunity. Finally the items the hog could dig up items depending on the biome, the most common in the forest biomes could be a wheat seed, deserts are cactus, snow biomes are ice, and mountains could be emeralds.
