FartBoost
FartBoost lets a player launch forward or high into the air with a fart-powered boost, and it is a Fabric mod for Minecraft 1.21.8.
What it does
The boost is a movement effect triggered by the player, pushing the character forward for a short burst or upward for a higher jump through the air. A cooldown can be switched on or off in game with a command, so a server can decide how often a boost is allowed.
Funny particle effects and custom sound effects accompany each boost, which is the main visual and audio change the mod makes to vanilla movement. It needs Fabric API to run, and Fabric is the only loader the files are published for.
Both the server and every player need the mod, since the boost is applied on both sides. The code is open source under the MIT License, and the source and issue tracker are public on GitHub. Files exist for 1.21.8 only, first published on 2025-08-09 and last updated on 2025-08-10, with version 1.0.0 as the latest file.
