I thought maybe it was a Gemmy prop and so looked on their site but they only have listings on the Butterfly and Fireflies in the jar. Even checked their halloween tab to see if it was listed there.
Doesn't seem to be a video of it yet on You Tube either.
I suppose you could turn some butterflies into bats though.
If I get into Publix again Ill see about getting a pic I too looked on Gemmys website and found nada as well as youtube.The packaging looked similar to Gemmys butterflys and fireflys so I assumed based on what I thought Gemmy had patent rights to that type of prop, I didnt look for a makers mark but I should have. :/
