Princess Sparkle was my childhood want, too! But I never got her, and still haven't added her to my collection - I'm kinda dreaming of getting her MIB one day, even though I don't collect MIBs otherwise.
I wanted Sparkle a lot as a kid too. And she was too expensive when she came out for my meagre pocket money. I mean, £10 was a lot of money in 1993 for a ten year old, right? But then we had this big toy store who had cheaper prices open and one of the things they had were loads of Princess Sparkle - but in French boxes. She was only £5 there, though. So I got her. Weird pony. No idea now why I wanted her so much then, but I love her French box and name, Lumiere.
I still have her box from childhood, but somehow I've also acquired an English box and I don't really know how I managed that O.o. I remember her name is Gloria in Germany, because another pony I got at this same kind of time was Birthday Pony from the same store - in a german box with a German insert! We had a lot of German packaged ponies show up here at the end of the line...I remember being kind of confused and kind of fascinated by it.
Birthday Pony is still Geburtstags-Pony to me, or Juli for everyday (because I bought her in July, and well, German for July.) I was really geeky at ten about wanting to speak French and German, so these two ponies made me much happier for their foreign boxes than I think they would have in English
