Nautilus Concept Add-on 1.21+

At the recent Minecraft Live 2025, the arrival of the Nautilus in upcoming Minecraft updates was announced. The creator of the mod Nautilus Concept quickly got to work and provided us with a model of the Nautilus in the game. In fact, the mob had already appeared in various modpacks before, since developers have long wanted to add a mob that drops the Nautilus Shell.

Unfortunately, the mob does not spawn naturally in the game. In the future, the author promises to also add Nautilus Armor.
