YY_I_AM
YY_I_AM is a Forge content mod for Minecraft 1.20.1 that adds new structures, blocks, mobs and a new biome to the game.
What it does
The mod brings new structures to the world, along with some blocks, mobs and loot that generate inside them. A new biome with its own blocks is part of the additions, so explorers can find terrain that vanilla worlds do not produce. The author describes the project as work in progress, and more structures and mobs are planned for later builds.
Because the mod changes world generation and spawns new mobs, it runs on client and server, so the server and every player need it. Files are published for Forge only, for Minecraft 1.20.1, and the latest build is 1.0.0, released on 2026-08-03. The code is licensed under All rights reserved, so the mod is not open source.
Key features
New structures
Structures generate in the world and hold blocks, mobs and loot for players to find while exploring.
New biome
A new biome adds its own surface blocks, so some areas of a world look different from vanilla terrain.
New mobs
Several mobs are added and spawn in the new structures and biome.
Loot
Chests in the added structures contain loot that players can collect during exploration.
