Ocean Overhaul

A deep-dive overhaul of Minecraft's oceans — a boss, a bioluminescent trench, apex gear, diving kit, aquariums, and the creatures and blocks to fill it all.

Features

What Ocean Overhaul adds to the deep.

Megalodon & Apex Gear

Hunt the Megalodon, a colossal apex boss shark, for guaranteed Megalodon Teeth, then forge the Abyssal Fang — an apex sword a full tier above Tidal (9 attack damage, 2200 durability, repaired with teeth).

The Abyssal Trench

Deep oceans now grow bioluminescent plankton and hydrothermal vents; giant clams grow Abyssal Pearls over a Minecraft day — return and right-click to harvest (empty clams drop nothing) — and the Megalodon and Abyssal Lurker concentrate down in the dark. Finding the deep is the deep-content gate.

Harpoon & Diving Kit

Throw a Harpoon that yanks your target back toward you and loyalty-returns to your hand. Equip Flippers (swim speed), an Oxygen Tank (water breathing) and a Deep-Sea Helmet (night vision) to make the depths traversable.

Aquariums

Bucket the mod's Reef Fish, Jellyfish and Seahorses — color variants preserved — and place an Aquarium block to watch your catch swim around inside a glass tank.

Tidal Gear

A full Tidal armor and tool set crafted from ocean materials, granting water-breathing and built for life below the surface.

Ocean Building Sets

Driftwood wood-set, abyssal coral, prismarine, pearl and sea-glass blocks — with stairs, slabs, walls and chiseled variants for true underwater builds.

Mobs

New creatures from the shallows to the trench.

Seahorse

Seahorse

A tiny solitary reef pet in five colors — bucket it (color preserved), display it in an aquarium, or let it drift near the coral it loves.

Shore Crab

Shore Crab

An amphibious beach scuttler — the mod's first walking and breedable mob. Hunt it for crab meat, breed pairs with kelp, and trim armor with its carapace.

Kraken

Kraken

A stationary trench boss: six independently-damageable tentacles guard an untouchable mantle — break the ring to open the kill window, and claim the Heart of the Kraken.

Megalodon

Megalodon

A massive apex boss shark that patrols the deep ocean and drops guaranteed Megalodon Teeth.

Abyssal Lurker

Abyssal Lurker

A bioluminescent anglerfish of the depths, its lure glowing in the dark.

Reef Fish

Reef Fish

Schooling tropical reef fish that bring color to shallow waters.

Jellyfish

Jellyfish

Drifting jellyfish in five distinct color variants.
