DatapacksJava
The Return of the Killer Rabbit of Caerbannog
I don't know my version or loader
Open the Minecraft launcher and look at the profile you play on — it names both, like fabric-loader-1.21.4. The version also shows in the bottom-right corner of the game's main menu.
No loader in the profile name? Then it's plain Minecraft, and these mods won't run — you need Fabric or NeoForge installed first.
A datapack/mod which re-adds the natural spawning of the Killer Rabbit from the popular comedy movie from 1975 'Monty Python and the Holy Grail' with a twist!
There is currently a 0.1% chance that the rabbit spawns naturally however if you name a Rabbit with its name, that will spawn it to. They also spawn with Speed 2 and Strength 10 to bring the rabbit in line with what we see in the movie!
You can edit the chance of it spawning in data/nie_rabbit/predicate/spawn_chance if you want them more or less common.
