Random Mob Riders
Random Mob Riders is a Fabric mod for Minecraft 1.21.11 that recreates a command-block-style system where mobs randomly ride each other, resulting in chaotic and dynamic mob stacking across the world.
✨ Features
- 🔀 Random mob stacking — mobs dynamically ride each other
- 🧠 AI-based filtering — only valid mobs (with AI) are selected
- 🚫 Excludes players and invalid entities
- 🎯 Accurate command logic — closely replicates in-game command behavior
- ⚡ Efficient implementation — no command blocks or forced chunk loading required
⚙️ How It Works
- Every tick, the mod runs logic similar to a repeating command block
- For each player:
- A random nearby mob (within 128 blocks) is selected
- The mob is tagged to prevent reprocessing
- Another valid mob is selected as a mount
- The first mob rides the second one
This results in naturally forming stacks of mobs throughout the world.

Projects on Modrinth are automatically available through a Maven repository for use with JVM build tools such as Gradle. To learn more about the Modrinth Maven API, click here.
Note: When available, you should use the creator's maven repo instead as it will have transitive dependency information that the Modrinth Maven API does not. You may also end up with duplicate dependencies if you use a mix of Modrinth and non-Modrinth Maven repositories for your dependencies, because the group identifier will be different when served through the Modrinth Maven API.
