I built some Pufferfish Mob Statues at a 1 pixel : 2 blocks scale. I made all three variants of the mob: small, medium, and big.
You can find schematics for LiteMatica and WorldEdit as well as a world with all statues in the download.
Feel free to download and use the statues however you like, but please give credit if you do :)
