About this Mod

📖 About:

The focus of Upgrade Aquatic is to improve content added in the Update Aquatic, including oceans, rivers, and insomnia. Our intent is to offer unique content, visuals, and gameplay while staying true to the feel of Minecraft. Some notable features are the Thrasher, a fantasy shark-like mob that uses sonar, thrashes anything it can catch in its jaws, and drops crafting ingredients for the trident; Renewable sand via bubble columns below sandstone; and Ocean Ravines spawning Prismarine Coral and Nautilus mobs!
