Coral Zombie Nautilus: Ocean’s New Threat
Explorers of warmer waters can now encounter a rare and dangerous new variant: the Coral Zombie Nautilus. This striking mob variant brings both visual appeal and increased challenge to ocean exploration.
Key Characteristics:
- Spawn Location: Warm Ocean biomes, replacing normal Zombie Nautilus

This change makes Camel Husk encounters more meaningful and provides better resource rewards for players exploring desert biomes or engaging with Mounts of Mayhem content.
