No Modern Mobs
by moonwirer
No Modern Mobs restores older mob behavior, changing which creatures spawn and how they act in a Minecraft world, with files for Fabric and Forge.
What it does
Removed mobs from earlier Beta releases return to the game through this mod. Enderman behavior from an earlier Beta release is included, and a zombie pigman appears in the Nether. A spider jockey, a skeleton riding a spider, is also added, which reintroduces a creature players of older versions remember.
The mod is server-side only, so players join a server running it without installing anything. It is released under CC0 1.0 Universal, which places the code in the public domain, and its source code and issue tracker are public. Optional compatibility with No More Structures: Essential is listed, though the mod does not require it.
Builds cover 1.20.1 – 1.21 on Fabric and Forge. Every file so far targets 1.21 as its latest version, and the first and most recent release was published on 2024-07-21.

Use cases
Older-style survival worlds
Players who want the mob mix of an earlier version can use the mod to bring back its creatures.
Who it’s for: The mod suits server owners who want older mob behavior on a multiplayer server, since only the server needs it. Players who join such a server need no installation.
How it compares
Spider Jockey, for Forge and NeoForge, adds the spider jockey on its own and is published for 1.20 – 1.21.8 under All rights reserved, which makes it closed. Actually Beta Nether covers Nether content and is released under the MIT License across Fabric, Forge, NeoForge and Quilt for 1.20 – 1.21.1. It works on either side, and neither the client nor the server needs it.
