Poisson Steve
by Mr_Crabe
Poisson Steve is a Forge mod by Mr_Crabe that adds a tamable fish-themed mob, a fish tank structure and a music disc.
What it does
The mod adds the Poisson Steve mob, which generates in a fish tank structure found in the overworld. A player can tame it with kelp. Once tamed, it follows its owner around until the owner right-clicks it to make it sit and wait. Right-clicking it with a costume makes the mob take that look, and the costume is crafted from four leather and one gold ingot. Its appearance also changes at random between 13 costumes, including the base one.
The mod also adds the fish tank structure and the costume as items. A music disc plays the Poisson Steve song, and the mob dances when the music is played. The mod is aimed at players who want a light, joke-style addition to a survival or creative world, and it is fairly simple in scope.
The mod requires Geckolib to run. It is published for Forge only, with a single file, 1.0.0, for Minecraft 1.20.1, released on 2025-04-19. Poisson Steve runs on client and server, so the server and every player need it. The mod is released under the Creative Commons Attribution 4.0 license and is not open source.

How it compares
Steve (Jack Black) Boss is a Forge mod for 1.20.1 with client and server environment, released under All rights reserved and not open source, so it is a boss-style addition rather than a tamable companion. Steve AI is an open source Forge option under the MIT License, covering 1.20 – 1.20.6 with client and server environment, which gives it a different version range from Poisson Steve. 086.jar is open source no, published for 1.20.1 – 1.21 and runs as server required with client optional, so players may join without it.
