I-oon's More Content Mod
by I-oon
I-oon's More Content Mod is a NeoForge mob and equipment pack for 1.21.8 that adds eight mobs, three weapons, a new ore and several items.
What it does
The mod adds eight new mobs, three new weapons, one new ore and a set of other items to the game. Two of the mobs are tied to specific biomes: Crystaliz appears in dripstone caves and gives access to a crystal block, while the Moss Golem is found in lush caves and drops moss spore blossoms when killed. A Giant Moss Golem, a larger version of the Moss Golem, attacks anything that strikes it. A new pink building block also joins the mod's content.
The Sea Cucumber lives on the ocean floor and can be bred with seagrass and kelp, and the mod adds a faster ocean floor, which the author describes as a basis for large sea floor builds. A Creeper Vaporizer Rod removes creepers from play. The author made the mod with MCreator and describes it as a first release, with one more mob still in development.
The mod runs on NeoForge and requires NeoForge itself, installed alongside Minecraft 1.21.8. Client and server share the content, so both the server and every player need the mod. Files are published for 1.21.8 only, and the license is All rights reserved, which means the mod is not open source.

Use cases
Who it’s for: Players on NeoForge 1.21.8 who want extra mobs and a few weapons in a single small pack. Server owners who want the content on a multiplayer world should install it on the server and on every client.
How it compares
Mosslings is a NeoForge mod for 1.21.1 that is client and server and not open source, so it targets an earlier version than this mod. Golem's Legacy is NeoForge for 1.21.8 only, but it is client-side only, so servers run without it, while this mod needs both sides. Triada covers Forge and NeoForge for 1.20.1 – 1.21.1 under the MIT License, which is an older range than this mod.

What the author says
This is my very first mod. This mod adds 8 new mobs (plus one I haven't finished yet), 4 new weapons, 1 new ore, and some new items. Made in Mcreator. You should download this mod if you want to have more mobs to play around with or if you want a fast ocean floor mount.
