I found a very cute frog mob made by Sully's Studios for his mod Sully's Mod that introduces a bunch of cool mobs to the game. I liked the little green guy so much that I created a Frog Mob Statues at a 1 pixel : 4 blocks scale.
You can find schematics for LiteMatica and WorldEdit as well as a world save with the statue in the download.
Feel free to download and use them however you like, but please give credit if you do :)
