The original Firefly was one of those ponies whose symbol simply did not make sense given her name. She has now been reborn as a G3, though, and things are different. Part of my Glitter and Glow series, she now has a glittery firefly on her flank, whose rear glows in the dark. Originally a Hidden Treasure, her entire look has been changed with deep blue hair just slightly darker than the original Firefly's, purple eyes, and a glow-in-the-dark star on her magnet hoof.

Firefly is for sale for $28 plus shipping. She has been discounted because her head and body are slightly different colors. This appears to be a factory flaw with the type or quality of plastic, as the Hidden Treasure in my collection also suffers from this problem.
