Change My Size

The mod adds a mini-potion game in which a regeneration potion, mini rotten flesh drops and baby zombies are combined with a fried dragon egg. Brewing that combination is what gives a player access to the size change, and it is the only route the mod describes for it. Each step of the process depends on the items being prepared in the right order, so the potion has to be finished before the size can be adjusted.

Once the size change is available, the player uses shrink and grow keys to adjust their character's height. The keys are assigned to settings that can be reassigned in the controls menu, and the current size can be checked at any time to confirm the result. A configuration file sets the minimum and maximum size, the frequency of mini rotten flesh drops, and the requirements for the potion and egg.

The mod is published for NeoForge only, with a single game version: 1.21.1. Servers that run it need every player to install it too. The code is released under the CC0 1.0 Universal license, which places the work in the public domain, but the project is not open source. The current release is 1.0.1, first published and last updated on 2025-08-13, and the author notes that the project is archived for updates.
