on

Minecraft 26.1 Snapshot 6 isn’t just another update—it’s a major release that brings two headline changes. First, a pack of adorable “feral” baby mobs has been redesigned with unique looks and animations. Second, the snapshot introduces the most significant overhaul of Minecraft’s world data format in years, impacting backups, datapacks, and mod compatibility.

This guide will walk you through both the cute new mobs and the critical technical updates, showing you how to upgrade safely and enjoy all the new features.

2. Part 1: A Closer Look at the "Feral" Baby Mobs

Snapshot 6 completely reimagines seven wild baby mobs, giving them distinct personalities and visual flair instead of just being mini adults.

3. Part 2: Understanding the New World Data Format

Minecraft 26.1 Snapshot 6: Baby Mobs & World Data Format Explained

Snapshot 6 brings a major reorganization of how Minecraft stores world files, aimed at improving structure, mod compatibility, and future updates.

📁 What's New in Your World Folder

Old Location (Root Folder)        New Location in Snapshot 6        What It Means
region/, DIM-1/, DIM1/dimensions/minecraft/overworld/ (etc.)Dimensions are now neatly organized.
playerdata/, advancements/players/data/, players/advancements/Personal progress and stats consolidated.
data/scoreboard.datdata/minecraft/scoreboard.datData is namespaced to prevent mod conflicts.
resources.zipresourcepacks/ folderWorld-specific resource packs relocated.

⚙️ Key Technical Changes

  • level.dat Updates: Now references player data differently and stores difficulty settings in text (“hard,” “easy”) rather than numbers.

  • Data Relocation: Info about the Ender Dragon fight, Wandering Traders, game rules, and weather now lives in organized files instead of level.dat.

  • World Generation Tweaks: Features like “forest_rock” are renamed to “block_blob” with more configurable placement rules.

Important Note: Snapshot 6 forces an automatic backup when you first load a world. Once upgraded, your world cannot be opened in older versions.

4. Part 3: Your Action Plan for Snapshot 6

4.1 How to Install and Test

  1. Enable Snapshots in the Minecraft Launcher under “Installations.”
