What it does

The mod changes mob sizes through a datapack, so the scale of each affected mob is reversed to the opposite of its default. The change applies to mobs in the game, including the most recent additions from the latest Minecraft update. It is published for Fabric, Forge, NeoForge and Quilt across 1.21.11 only, with snapshot builds available.

Because the effect comes from a datapack, it is applied on the server side and needs no client installation to take effect for the server's world. Only the server needs it for the change to apply, and players may skip installing it. The code is under the Apache License 2.0, and the project is not open source.

The mod is suited to servers and single-player worlds where scale changes are wanted for novelty or for a playthrough with unusual mobs. Its author notes a test video showing the inverted scale in action.
