Update 1.20 has been around for a while and I finally created some Sniffer Mob Statues at a 1 pixel : 2 blocks scale!
There are two variants: The standard Sniffer and the Sniffer lying down to start digging for seeds.
You can find schematics for LiteMatica and WorldEdit as well as a world save with the statues in the download.
Feel free to download and use the schematics however you like, but please give credit if you do :)
