This is a small mod that will overwrite most of the pony creature files in your game. The result is that every caste of every creature has a unique tile, so you can tell who you're looking at, either in your own fortress or in your enemy's attack force, at a glance.
Designed for Dsarker's My Little Fortress update. Simply drop the contents of the .zip folder into your raws folder with My Little Fortress 2 installed.
