SCP-524, Walter the Omnivorous Rabbit

Walter the Omnivorous Rabbit adds a single anomalous entity taken from the SCP universe, where it is catalogued as SCP-524. The rabbit has pale fur, dark ears and a dark snout. It spawns on the surface of the overworld wherever the ground is grass, dirt or mud, and only one instance exists in a world. It is passive by default and only fights when provoked, and then it eats its attacker.

The rabbit can consume blocks in front of it when it is hungry, and it will eat any item a player gives it. Each eaten item is permanently removed and heals the rabbit while granting experience to the player. Taming requires a Golden Carrot, after which the rabbit stays loyal, will not attack its owner and will defend the owner. Its spawning follows the same rules as the rest of the mod's mobs, which are controlled by conditions that determine where and when a mob may appear.

The mod requires Geckolib, and it runs on client and server, so the server and every player need it. Files are published for Forge only, for 1.19.2, 1.19.4 and 1.20.1, and the latest file is 1.0.0 for 1.20.1. It is released under All rights reserved and is not open source.
