Spring to Life Backport
by MC-Backports
Spring to Life Backport brings several 1.21.5 Spring Life features to Minecraft 1.21.1, adding new animal variants, eggs and vegetation for world generation.
What it does
Chickens, cows and pigs gain warm and cold variants, and two new egg types, blue and brown, can be obtained through recipes and used in crafting. Each variant covers its own drops, spawning and breeding behaviour, and the variants appear in world generation along with the new plants.
Leaf Litter, Firefly Bush, Short Dry Grass and Tall Dry Grass are added as decorative vegetation that generates in the world. The backport targets Fabric, Forge and NeoForge, and Fabric API is required on Fabric. Installation covers the server and each player's game. Builds cover the 1.20.1 – 1.21.1 span with 1.3.3 as the latest file for each loader.
The mod is open source under the GNU General Public License v3.0 only, and its source code and issue tracker are public. The first release was published on 2025-05-05 and the last update on 2026-03-23. Field ambience audio used in the project is licensed under Creative Commons 0 and other terms noted by the authors.
