Minecraft Java Edition Snapshot 25w02a, released January 8, 2025, adds cold- and warm-biome pig variants, Wildflowers, Leaf Litter, and falling-leaf particles. It also revises the Lodestone recipe. This is a historical Java testing build, not the current Minecraft version; Wildflowers, Leaf Litter, and falling-leaf particles later appeared in the Java Edition 1.21.5 release notes.
What’s new in Minecraft snapshot 25w02a?
The Java Team described the update this way: “This snapshot adds new ambient features to the game, including wildflowers, leaf litter, and falling leaves.” The most visible additions are biome-specific pig appearances and decorative details for forests and meadows. The snapshot also makes Lodestones cheaper to craft in iron.
Where do cold and warm pigs spawn?
Pig appearance is determined by the biome where the pig spawns. Temperate pigs remain the default in biomes that do not spawn either of the new variants.
Cold pigs
Cold pigs spawn in Old Growth Pine Taiga, Old Growth Spruce Taiga, Taiga, Snowy Taiga, Windswept Hills, Windswept Gravelly Hills, and Windswept Forest.

Technical changes

How to try the snapshot safely
- Open Minecraft Launcher and go to the Installations tab.
- Enable snapshots in the launcher, then create or select an installation for the snapshot.
- Back up any world you plan to use, or run the snapshot from a folder separate from your main worlds. Mojang warns: “Testing versions can corrupt your world, so please backup and/or run them in a different folder from your main worlds.”
These instructions apply to Java Edition snapshots. The January 2025 overview described Bedrock testing through Preview/Beta separately; at that time, falling-leaf particles were available there while Wildflowers and Leaf Litter were still forthcoming. That was the status then, not a statement about current Bedrock availability.
