I built a Cow Mob Statue and decided to make some for the Mooshroom mobs as well. The scale is 1 pixel : 2 blocks.
The download includes a world with the statues as well as schematics for Litematica and WorldEdit
Hope you like 'em! :)
Feel free to download and use the statues however you like, but please give credit if you do :)
