Nautilus

Nautili are passive mobs that spawn in oceans.

Appearance
Nautili are based off the chambered nautilus and the vanilla Nautilus Shell item, and are white in color, with a brown underside, red, pink, and orange stripes on its shell, a pale brown hood, and a dark grey mouth hiding in its tentacles.

Behavior
Nautili make no attempt to interact with any nearby players and mobs, and just aimlessly swim around. When swimming, they will float in place for a short amount of time before propelling themselves forward a great distance. Unlike squid and jellyfish, however, they seem to be capable of swimming around obstacles to some extent.

Nautili can be caught by using a water bucket on them; when this bucket is used on a block, it immediately empties, placing a source of water with the nautilus inside of it.

If a nautilus gets beached on land, it will start suffocating after 20 seconds. While on land, nautilus will not move, and will stay in place until they die; as well as this, they are extremely resistant to knockback while on land.
