Perfect Quad Village in a Mountain Bowl
Spawn inside a mountain bowl containing a perfectly spaced (144 blocks apart) quad village.
Mountain Circle with All Wood Types, Including Mangrove
As many may know, swamps can’t generate inside mountain circles, so since 1.18 the idea of a mountain circle containing every wood type has seemed impossible. However, with a specific type of trial chamber, a naturally generated mangrove tree can appear beneath it. This seed does exactly that.
All Overworld Wood Types Within 175 Blocks of 0, 0
This seed has every Overworld wood type within 175 blocks of 0, 0. I can’t test on Bedrock, and since tree generation differs from Java, the distance may be closer to 180–200 blocks, but all wood types should still be present.
Huge Cherry Island Over 1,000 Blocks from the Mainland
This seed features an extremely rare cherry grove island that is both large in size and immensely isolated!
Cherry Island Nestled Between Two Villages
This is a ridiculously rare seed that required a very unusual noise-map configuration to generate. The result is a highly scenic cherry island positioned between two villages. The island itself works on both Bedrock and Java, while the villages generate on Java only. Hope you all enjoy!
18k block continent with all biomes for Bedrock and Java, and all structures (Java only)
This is the largest continent ever found in Minecraft (that I am aware of). It was found using a custom program made by me, is 18k blocks long and 14k wide, and has every biome for Bedrock and Java, and every structure for Java. The only missing structure for Bedrock is the woodland mansion. There are WAY too many POIs to share, but I will link a map of the seed on mcseedmap.net so you can explore!!

Large Pumpkin Patch
One of the largest pumpkin patches I’ve ever seen (it’s actually two, just very close together). There are exactly 50 pumpkins at 150, 250 . May many pumpkin pies be in your future! Screenshot taken with Iris shaders.
Village with Access to Almost Every Wood Type Nearby
Having trouble finding wood to build with? Now you don’t have to. With this seed, you spawn right next to a village surrounded by almost every wood type in the game: pale oak, dark oak, oak, birch, spruce, and jungle — with cherry wood almost directly north (negative Z) at 200, -800 . Screenshot taken with Iris shaders.
Cherry Blossom Biome with Village in Crater
This seed spawns you beside a massive crater, ringed by a cherry blossom biome, with two villages nestled right in the center . It’s one of those rare world-gen moments that looks unreal in-game - my screenshot honestly doesn’t do it justice.
Rare Swamp Village
Taiga village extending into swamp area, allowing natural swamp villager spawning. Swamp villagers don't normally spawn, but this seed's unique village placement allows them to generate naturally. This seed was originally discovered via a public roundup on PCGamesN. It has been reuploaded here with a custom title, description, and screenshot to help populate the site. If you are the original finder of this seed, or know who is, please get in touch and proper credit can be added - or ownership transferred if they have a seedb account.
