Holoecho: Monster of the sea

There should be a mob in Minecraft known as the holoecho (hol-o-ek-o). It is a mob that lives in the sea. It can spawn in any ocean biomes except the frozen ocean and the deep frozen ocean. It is as strong as the elder guardian. It looks similar to a shark. It shoots these sound waves to travel. It shoots a sound wave to see if there is a wall or not. The sound wave destroys any sand or gravel in its way. If TNT gets in the way of the sound wave the TNT explodes. Any mobs in its way take damage from the sound wave. Any mobs in the sound wave’s way also get attacked by the holoecho. Any players also get attacked by the holoecho if in the way of the sound wave. When killed it drops a sound wave charge.
