The Killer Rabbit of Caerbannog Returns

Transform ordinary rabbits into deadly monsters! This datapack or Minecraft mod revives the appearance of the legendary killer rabbit, known from the iconic comedy film "Monty Python and the Holy Grail", but with a twist!

Spawn Mechanics: The main feature is a 0.1% chance for the dangerous beast to spawn naturally in the world. But there's another way—name an ordinary rabbit with the appropriate name (e.g., "Killer Rabbit"), and it will transform into a bloodthirsty monster! Additionally, to convey its ferocity from the movie, the rabbit is endowed with Speed 2 and Strength 10 effects.

It's important to know that the rabbit's parameters will adapt to in-game conditions if increased difficulty is needed, though scaling issues rarely occur.
