ChaosBreak
by tenshinoyona
Breaking any block with ChaosBreak spawns one random vanilla mob at that spot, so even a simple mining trip can turn into an encounter.
What it does
Each time a player breaks a block, the mod spawns one mob chosen at random from the vanilla roster. The pool gives every entry an equal chance, so a harmless animal and a dangerous monster are equally likely to appear. Mining deep underground, cutting a first tree or clearing a stone patch all carry the same gamble. The Ender Dragon is left out of the pool by default, which keeps normal progression possible; the source code can be edited and rebuilt by advanced users to change that choice.
The mod is a server-side only addition, so only the server needs it and players join without installing anything. It works in singleplayer and multiplayer alike. It depends on Fabric API and needs Fabric Loader 0.19.3 or newer. It adds no new items, blocks or mobs of its own, using only vanilla entities. Files are published for Fabric alone, for game version 26.2, and the code is licensed under the PolyForm Noncommercial License 1.0.0, which is not open source.
Key features
Random mob per broken block
Each broken block spawns exactly one vanilla mob, so the spawn is tied to the act of mining or chopping.
Equal chance pool
Every mob in the pool has the same chance of appearing, so passive animals and deadly bosses can show up alike.
Ender Dragon excluded by default
The dragon is left out of the spawn pool so that the main progression path remains reachable.
Lightweight design
The mod changes the survival experience without adding new content, relying only on existing vanilla entities.

How it compares
Mob Roulette is server-side only, published for Fabric and 26.1.2, and is not open source under All rights reserved. Wild Behavior is also server-side only and not open source, with Fabric files for 26.2, the same version as ChaosBreak. Boss Drops targets 26.1.2 with a client and server environment, so both sides must run it, and it is not open source either.
