Minecraft Java and Bedrock edition, rod elementals

What this would add is 2 new mobs similar to the blaze and breeze, and would allow players to make the element paintings. The new mobs would be the bolder a mob that shoots rocks at you and can tunnel in the ground, and the bay a water mob that can shoot tidal waves at you from the water. This would also add the items, earth charge and water charge, and would work like these mob's attacks. Both mobs would be found in a special biome or structure. The paintings would be made using the in game charges (fire, earth, wind, and water).  I think it would be awesome to see all four elements imbodied in the game.
