About this Mod

The mod is archived and will not receive updates.

Adds a mini-potion to the game, which can be made from a regeneration potion and mini rotten flesh, which drops from baby zombies and a fried dragon egg.
After using them, you can shrink and grow using the - and = keys, and also find out your size using \ (can be reassigned in the control settings)

In the configuration file, you can configure the frequency of mini rotten flesh drops, the need to use a potion and a fried egg to change the size, and the minimum/maximum size.
With the /changemysize_set_tags command, you can change the tags for using the potion and fried egg.
