Gas System
by PerryRat
Gas System adds in-game flatulence to NeoForge 1.21.1, letting a player release gas as a character action with sound and effects.
What it does
Players release gas as a character action, and the mod presents the act as a visible and audible part of the avatar rather than a silent one. The author describes the feature as giving a character more presence, though the page itself makes no claims about how players will react to it.
A server running it needs every connecting player to have it too. Files are published for NeoForge only, for Minecraft 1.21.1, and the latest build is 0.9.5 from 2025-06-24. The code is under the MIT License.
Key features
Release gas action
A player can release gas as an action, with the effect shown on the avatar.
Avatar presence
The character gains a noticeable body presence, so the act is visible to others nearby.
Adjustable silence
The mod is framed as an alternative to quiet play, adding a sound layer where a game would otherwise be silent.
Atmosphere flavor
Its purpose is comic atmosphere rather than gameplay balance, so the effects serve mood and humor.

Use cases
Comedy servers
Groups that want a lighthearted, joke-driven environment can run the mod for its absurd novelty.
Roleplay jokes
Players who build comic characters can use the gas action as a recurring gag in their scenes.
Who it’s for: Players and server owners who want a comic, deliberately silly addition for NeoForge 1.21.1 games. Both sides need the mod for the feature to work across a server.
