Princess Baby Buggy
I sincerely wish that Hasbro in the UK had decided to issue this version of the Baby Buggy here, because I know that it would have sold like mad. The Baby Buggy got it's upgrade in the North American pony line in 1991, with the canopy now embedded with specks of glitter, and the lace woven with silver strands. The wheels too were glittery and the main carriage dark pink, in fact, only the main chassis seems to have stayed the same.
Baby Princess Sparkle was the only baby pony sold in North America to have tinselled hair, and she also had a glittery castle symbol, plus a glittery gold star on her forehead (so yes, she's fairly easy to spot even when seperated from her buggy!). The buggy came with a soft pink blanket and a white and silver mesh ribbon (Sparkle has this around her neck in the picture, if you can see it), but I'd have to get my box down from the attic to know what else :)
Sparkle's hair easily fades to white, but this is not a variation, simply sun-damage :-/
