Telling a Killer Bunny Apart from a Normal Rabbit
Visual Differences
A Killer Bunny looks like a normal rabbit but has a distinctly different appearance — most notably a more aggressive, hostile look compared to the peaceful white or brown rabbits. In vanilla Minecraft the Killer Bunny is white with red, angry eyes and a menacing expression. Watch for that red-eyed, hostile variant when your bred babies grow up.
Behavioral Clues
Normal rabbits flee from players and most mobs. A Killer Bunny does the opposite: it charges and attacks. If a baby rabbit grows up and immediately lunges at you or nearby animals, it is a Killer Bunny.
Checking Your Bred Babies
Observe it from outside the pen first. If it hops toward you aggressively rather than running away, treat it as a Killer Bunny and isolate it.
Why It Matters
Knowing which rabbits are Killer Bunnies lets you control your breeding stock. If you only want normal rabbits for a peaceful farm, remove or contain the Killer ones. If you are farming Killer Bunnies on purpose, keep them separated so they do not attack your normal breeders.
