Great job! There's only one that hasn't been correctly guessed, and that's Seaflower. Again, some of them have multiple possibilities, but here's the intended targets for the ones that have been guessed:
Blue Belle = josiekat
Sugarberry = Strawberry Fair
Cherries Jubilee = Cannibal Cow
Gingerbread = Ginderbread
Skyflier = Skyflier (yes, Starflower's sister)
Red Roses = Kar Red Roses
Wind Whistler = EVERYONE at the TP
Skippity Doo = Skippety Doo (note the spelling hehe)
Sherbet = me, Sherbet
Seaflower = ?
Some of the answers were really interesting to read. I also had Gusty and Minty with me and forgot to get them in the picture. Minty would be for StevesMinty and Shlugh, and others I'm sure, and Gusty for several people including Gusty325, MariosGusty, GustyFox, UnicornGusty, etc.
edit to add: I think that Seaflower needs a bit of a clue... it's not this person's name, but she once took an amazing picture of her Seaflower that always makes me associate that pony with her.
