Y’know, this G4 redesign of her is quite cute. I’d like to see more old characters come back, like they’ve been doing in the new TMNT Nick show & Sonic comics. (BTW Casey Jones now has his original badass hockey mask. W00! I didn’t like his new one much.)

She’s the ENFP to Wind Whistler’s ISTJ, which is why I ship it they round each other out so well.

She’s been crystallified as well, hence the hexagonal eye reflection. Perhaps that’s the nearest G4 equivalent?
 
 
To be perfectly honest, I’m not completely sure what makes a crystal pony appear the way they do.  
They’re clearly perfectly ordinary little ponies other than their relationship with the naturally occurring crystalline rocks found in this area of Equestria. I have the hypothesis that when they’re feeling strong emotions, especially love, part of the natural illumination that’s incident upon their coat, eyes, and mane becomes briefly refracted into a realm of pure crystal to which they are magically attuned. We see the reflected portion of that as something resembling the pattern of an opal, but as a ghost-image that seems to come from within the little pony. Yes, I must take you away for further study… my goodness, Fizzy - you’re going it now! And why are you looking at me like that?

Yeah she really isn’t dumb just a bit of an airhead at times.

Fizzy definitely isn’t dumb (shouldn’t her eyes be jeweled though?). She’s cute! :D

She’s not dumb! Just a bit sweet & Pollyanna-ish.

Another great G1 character, one of my favorites for sure.

Cutest crystal (twinkle eyed) pony ever!
