Warm Ocean

Warm Ocean is a tropical ocean biome that generates in the hottest temperature zones of the Overworld, typically appearing alongside deserts, mangrove swamps, and occasionally windswept savannas. It may border lukewarm oceans, deep lukewarm oceans, and mushroom fields, but never shares a direct boundary with badlands biomes. Where a deep warm ocean variant once existed as a separate type, the Warm Ocean now simply generates at twice the standard depth in those locations.

The ocean floor of the Warm Ocean is layered with sand over stone, and conspicuously lacks the dirt, clay, and gravel found in shallower portions of other ocean types. Its most recognizable feature is the dense coral reef ecosystem that spreads across much of the seabed, accompanied by clusters of sea pickles. Kelp does not grow here, setting the Warm Ocean apart from cooler ocean biomes. The water itself carries a distinctive aquamarine tint visible from the surface.

Tropical fish and pufferfish are the unique aquatic mobs that spawn in this biome, while cod and salmon are entirely absent. Dolphins, squids, glow squids, and nautiluses also inhabit these waters, and any zombie nautiluses encountered here appear in their coral variant form. Shipwrecks and warm ocean ruins can be found scattered among the reef formations.

The Warm Ocean is a practical destination for players collecting coral blocks, sea pickles, or tropical fish. The intricate reef structures can complicate underwater navigation but create a visually dense environment. When Vibrant Visuals is enabled, a semi-humid volumetric fog adds a subtle atmospheric haze to the biome's distant horizon.
