Glitch Mob
by GamerJig
Glitch Mob adds glitch-themed entities, tools, ores and items to Minecraft 1.21.8, with a Glitch Sword, a Glitch Pickaxe and a backpack for storage.
What it does
A Glitch mob appears in the world, and the mod adds a set of glitch-related materials that players can gather from Glitch ores found across the terrain. Those materials are used to craft the Glitch Sword and other glitch-related equipment, and the Glitch Pickaxe is intended for mining and collecting resources. The author describes the content as unfamiliar items, materials and entities that do not appear in vanilla.
The mod also includes a backpack that holds stuff for carrying items around. An apple eaten in the mod gives strength and more health. Glitch Mob runs on client and server, so the server and every player need it. It is published for Fabric and NeoForge, with files for 1.21.8 only, under the MIT License, and is not open source. The latest Fabric and NeoForge builds, 1.1.0 for 1.21.8, were released on 2026-06-25, and the mod was first published on 2026-06-19.
