Balloonies

Balloonies adds balloon mobs that generate in four biomes: Plains, Sunflower Plains, Snowy Plains and Meadow. The mobs come in five variants, and most of them share the same drops and events when they pop. Some balloons carry a face, and each one can bring a surprise along when it pops.

A new Blue Rose flower is part of the set. It is a cosmetic plant with no effect on gameplay. A White Balloonie variant is listed as a dropped version, and a separate scary White Balloonie variant is described in the author notes. Scary balloons explode when they touch players, so they are a threat rather than a decoration.

The mod is client and server, so the server and every player on it need the mod. The files are for Fabric and 1.21.1 only, and the source code is under the MIT License, which makes the project open source. The author says more features will follow in later updates, and a working build is expected in about two months.
