"Upside down is right way up!"

Wing Dings were produced by Hasbro in 1986. They were a small series of plush 12" high animals with glow-in-the-dark features, designed to hang upside down like bats. They each had a pair of wings which they could wrap themselves up in and a differently patterned belly.

I can't find any information about this series on the internet, so if you know anything else about Wing Dings please email me!
