Ocean ruins are structures primarily composed of stone bricks or sandstone. They are found in ocean biomes and rarely on beaches. They contain chests, suspicious sand, and suspicious gravel, which hold a variety of loot, notably the buried treasure map and the sniffer egg. These ruins have cold and warm underwater variants that vary from large villages to single ruined huts.

Generation

Cold ocean ruins generate in normal, cold, and frozen ocean biomes or in their deep variants. They are composed of stone materials and contain some suspicious gravel blocks that can be excavated using a brush.

Warm ocean ruins generate in warm, lukewarm, and deep lukewarm ocean biomes, and are composed of sandstone and stone materials as well as having some blocks of suspicious sand within them.

Ocean ruins may at times be at least partially buried, including with their airspaces. During generation, all air blocks and structure blocks act as structure voids. This means that their associated suspicious blocks are also located under layers of usual sand, gravel, and even stone.

Suspicious sand and gravel randomly replace sand and gravel respectively during generation, and are not part of the structure definition.

Although most ocean ruins generate underwater, they sometimes generate on land, bordering a beach or another seaside biome.

30% of ocean ruins generate as large ocean ruins; the other 70% generate as small ruins. If the ocean ruin is large, there is a 90% chance for 4-8 (inclusive) small ocean ruins to generate around it in a cluster. If the ocean ruin is warm, large ocean ruins generate with a structure integrity of 0.9 and small ocean ruins generate with a structure integrity of 0.8. If the ocean ruin is cold, the "brick" variant of the chosen structure type generates with a structure integrity of 0.9 if large and 0.8 if small. The "cracked" variant generates with a structure integrity of 0.7 and the "mossy" variant generates with a structure integrity of 0.5, both regardless of size. Reduced structure integrity may also remove drowned from the structures.

Structure

The shape and size of ocean ruins varies greatly, and they often generate together in groups to create ruined villages.

All but two of the structures contain a loot chest with loot inside. The chest contains loot for specifically either a small or large sized ocean ruin structure and may be buried under blocks such as gravel and sand.

Cold ocean ruins are primarily composed of stone bricks, gravel, and suspicious gravel, and they also contain prismarine, sand, magma blocks, sea lanterns, polished granite, glazed terracotta, bricks, planks, cobblestone, mossy cobblestone, stone brick stairs, obsidian, or a chest with loot in it. Warm ocean ruins are primarily composed of sand, sandstone, and suspicious sand, and they also contain polished granite, polished diorite, sea lanterns, magma blocks, gravel, terracotta, sandstone stairs, or a loot chest.

Many of the structures spawn with drowned (usually one or two, though a few structures have three or four).

Natural ocean ruins generate following the rules above and may not exactly match the stored structures.

The structures below are located in the folder client.jar/data/minecraft/structures/underwater_ruin. The following is a complete table of the structures with their filenames, descriptions and what they consist of.

Each structure block indicates either a chest with random loot or the spawn location of a drowned mob.
