"Upside down is right side up!"
Wing Dings were produced by Hasbro in 1986. They were a small series of plush creatures with glow-in-the-dark features, designed to hang upside down like bats. They each had a pair of metallic fabric wings which they could wrap themselves up in and a differently patterned belly.
"Their wings wrap snugly or open wide so you can hug 'em up and hang 'em up!"
There were six Wing Dings produced and were 12 inches high. They came hanging upside down in their boxes from a little yellow plastic coat hanger.
