If I Had the Wings of a Bugaloo - S1-E5
Other mistake: Joy's feet are stuck in Benita's glue trap, but she steps backwards twice before Harmony and Courage pull her out.
Revealing mistake: Woofer and Tweeter were often seen hanging off the back of Benita's car. From the way the front of their costumes are flattened out you can tell they were lying on a flat surface to get the effect of them flying.

Sparky: I can't fly.
Harmony: But you're a firefly, fire...fly.
Sparky: I tried it once, scared me to death.
Lady, You Don't Look Eighty - S1-E13
