I built a couple of Bat Mob Statues at both a 1 pixel : 1 block scale and a 1 pixel : 2 blocks scale. For both scales there are three bat variants: hanging upside-down, flying upright and flying at a 45 degree angle. So there are a total of six statues in the download.
You can find schematics for LiteMatica and WorldEdit as well as a world save with all the statues in the download.
Feel free to download and use the statues however you like, but please give credit if you do :)
