Pilot nautiluses!

Pilot nautilus armor is crafted with normal nautilus armor, elytra, and a water breathing potion(so the nautilus can breathe on land). In the water, it acts like normal nautilus armor, but if you jump up out of the water, the elytra wings deploy, and so does the scuba mask for the nautilus. Flying on a pilot nautilus has the same controls as a happy ghast, but the pilot nautilus is much, much faster. You also have an air ram so you can damage flying hostile mobs. There is also phantom pilot nautilus armor, which is even faster, and has a swoop attack instead of the ram. It's crafted with diamond or netherite pilot nautilus armor and a phantom membrane. There's also pilot armor for players that lets you parachute down from high heights. There's also pilot drowned on pilot zombie nautiluses that can fly up and ram you off your pilot nautilus.
