Cute vampire bat playing the violin key ring

What song could this cute "3-D" vampire bat be playing on his violin? This design is just right for so many occasions: birthdays, recitals, birth announcements, baby showers, and any others you can dream up! Feel free to add your own words to this design too. You can make the picture smaller, bigger, or move it around if you'd like with the +/- and arrows to make room for your words -- maybe a special someone's name? You can also change the background colour via the customisation tools!
