D&D bat dragon

this is a mix of a dragon (specificly a fire dragon, but can be any other dragon) and a bat. i got this idea when my DM told me to pick between a fire dragon and a bat, so i chose both! since i got the idea myself it doesn't have rules yet such as HP or DMG, but i'd appriciate it if someone put them in the comments! And for all the legendary DM's out there (all of em), i recommend suprising your players with this beast! it will be hilarious! if yall have ideas for me or tips for this specific 3d-model, feel free to tell me in the comments!
