ERZ: Unbound
by ALEXYSSSJ4
ERZ: Unbound reworks the Ember Root Zoo mobs for Forge 1.20.1, adding a cursed cat, a toxic witch, a confusion creeper and a rainbow slime.
What it does
The mod is a reimagining of the Ember Root Zoo mobs, rebuilt from the original by ALEXYSSSJ4 with fixed bugs, new textures and animation improvements. Its cursed cat looks ordinary at first glance, but it can turn into a wild beast to defend its owner, and it is immune to poison and wither. Players can tame a cursed cat with pufferfish or tropical fish, and feeding it a pufferfish restores full health at once.
The toxic witch is a harder version of the normal witch. She uses persistent slowness potions and wither potions, keeps one or two cursed cats as protectors, and heals herself when injured in combat. Crafting a wither potion takes a mundane potion and a wither rose. Creepers of the confusion type carry an unusual effect that depends on their color, and baby electric variants appear naturally when struck by lightning. The rainbow slime comes in size-based forms that leave clouds with potion effects, and it can be carried around in a bucket.
The mod needs Forge and is published for 1.20.1 only, with the latest Forge file, 1.9.3 for 1.20.1, dated 2026-04-15. Every player and the server need a copy of the mod. It is released under All rights reserved and is not open source.

How it compares
Golden Cat Boss is a Forge mod for 1.20.1 that also runs on client and server, but it is released under All rights reserved and is not open source. Better Wither is a server-side only Forge mod for 1.20.1, so players join without installing it, and it is not open source. Cat Herder is an open source mod under the MIT License for Forge 1.18 – 1.18.2, so it does not cover the 1.20.1 build.
