Coolstuff
by Wentory
Coolstuff is a NeoForge mod for Minecraft 1.21.1 that adds absurd and surprising mechanics to familiar mobs, projectiles and items.
What it does
Ghasts gain new behaviour. A player who parries a fireball with a successful hit sends it back faster and stronger, and each parry opens further fireball phases. After one hundred parries a black hole is created. Some ghasts occasionally parry fireballs back at the player, and UltraGhasts can fire several fireballs at once.
Other mobs and items change as well. Spore Creepers launch themselves at their targets, and Frostlings throw snowballs that can cover the screen in snow. Cakes can be thrown, and they carry fillings with special effects. The mod keeps the original feel of the game and adds to the core gameplay rather than replacing it.
Coolstuff is open source under the MIT License and is published for NeoForge only. Files cover 1.21.1 and the environment is client and server, so the server and every player need the mod. The latest NeoForge file is 0.1.2, released on 2026-08-30. It is one of 1762 Cursed mods with NeoForge files for 1.21.1.
Key features
Parrying ghast fireballs
A successful parry speeds up and strengthens the returned fireball, and the parry count opens new fireball phases.
Black hole after 100 parries
Reaching one hundred parries creates a black hole, a late-stage effect for players who keep parrying.
UltraGhasts and parrying ghasts
UltraGhasts fire multiple fireballs, and some ghasts occasionally parry fireballs back at the player.
Thrown cakes and frost
Cakes can be thrown with a range of fillings and special effects, and Frostlings cover the screen with snow.

How it compares
PARRY! is a NeoForge mod for 1.21.4, and only the client needs it, so servers run without it. Its license is the MIT License. Parry It! targets Forge and NeoForge for 1.20.1 – 1.21.1, with the client and server both needing it, under All rights reserved. Shield Parry is also a NeoForge mod for 1.21.1 under the MIT License, and it must be on both sides.
