Hello, mods! o/

In regards to full moon transformations for vampires, I read they lose their human appearance and become monstrous bats. Super great if you ask me. I'm trying to imagine it in my head and I know there's different species of bats, but was also wondering if something creepy like this is possible for that transformation?? I didn't want to assume or anything so hence my asking. Let me know if that is cool or he needs to be more like... small bat-like.

Thank you! c:
