Luna's UpdateMize o4!
by SushiMCPE
Luna's UpdateMize o4! is a NeoForge mobs mod for 1.21.4 that brings some Minecraft Live 2025.1 features to the game early, centered on the Ghastling and Happy Ghast.
What it does
The mod adds Dried Ghast variants in sad, neutral and smiling forms. Dried Ghasts can be found near Nether fossils and picked up, then placed in water in the Overworld. After some waiting, a Dried Ghast turns into a Ghastling, and a Ghastling later turns into a Happy Ghast sooner when fed snowballs. Happy Ghasts can be fitted with a Harness made in 16 wool colors, and a harness lets a player ride one with up to three other passengers.
The mod is a recreation of features from Minecraft Live, packed into one NeoForge mod, and it is not an official release. Its version scheme is its own, with o4 standing for omega-4, the fourth update of the UpdateMize series. Spawn eggs for the Ghastling and Happy Ghast are in the Creative inventory. Files are published for NeoForge only, for 1.21.4, and the mod runs on client and server, so the server and every player need it. The mod is not open source, and it is released under All rights reserved.
