Upgrade Aquatic introduces a diverse array of new mobs to Minecraft, with a focus on enhancing ocean and river biomes through realistic aquatic life and interactive mechanics.

These mobs encompass a diverse range, from passive and decorative species to aggressive predators and transformative entities, all designed to seamlessly integrate with vanilla gameplay while enhancing the marine ecosystem.

Aquatic Creatures

Pike

A predatory fish found in rivers that attacks smaller fish and can pick up or spawn with items from the fishing loot table. Comes in 21 biome-specific skins and drops raw Pike and bone meal.

Perch

A passive fish found in rivers. Hunted by Pikes and drops raw Perch on death. It can be captured in a Bucket.
