Buttwings 

Buttwings are small wings that can be found on the rear-end (butt) of something; they are generally found on non-existent things like Victini and anything that's free to buy.

Victini has a pretty prominent, but small pair of Buttwings that allow it to fly around and cheat the laws of physics.
