Aquatic Weirdos
Aquatic Weirdos adds a set of odd sea and swamp creatures to Forge, each with its own drops, effects and habits, for worlds that have any water in them.
What it does
The mod introduces several strange aquatic animals that live in oceans, swamps and other bodies of water. Each one has a distinct look and behavior, and most of their drops feed back into the game as usable items. The Man o War floats on warm ocean surfaces and stings anything that touches it, and its tentacles can be sheared off to hang from ceilings as decoration or defense. A Man o War without tentacles can no longer sting. The Barreleye lives in deep cold oceans and has transparent heads that let it spot predators and prey above it, and eating its cooked meat is not possible, since its drop gives a Barrel Sight effect that makes entities behind walls glow.
Aquatic Weirdos requires Geckolib, which must be installed alongside it. The mod is built for Forge and published for Minecraft 1.20.1 only. Servers that run it need every player to install it too. The code is released under the MIT License, which is not open source.

GreGille BETA runs on client and server with All rights reserved, also for 1.20.1. Deep Blue: A Bettas & Aquatics Addon! is client and server with All rights reserved, and covers 1.18.2 – 1.20.6 on Forge. Aquatic Weirdos sits between these, a Forge-only client and server mod for 1.20.1 that adds creatures instead of blocks.
