-I think pink bodied Sweet Clover was released in the UK, and peach bodied Sweet Clover was released in Germany only. So peach-Clover may be Nirvana in your books, same with pale Speedy? It might depend on if you exclude Swirly Whirly with aqua hair and Coco Berry with lavender hair from the regular releases too.
-I believe there may be variants of Rosette, from the UK/Euro Prize Day Playset. I think there was a thread in the Corral ages ago discussing her hair colours - one version has orange hair with a single yellow stripe, whilst one has a whole horizontal row of yellow hair and one row of orange hair? And perhaps one of them was the UK version and one of them was a German variant, like Sweet Clover? I'm really not sure on this point, maybe someone can correct me.
-Yellow Moondancer? MyLittleWiki has her as a Euro release, some sites list her as UK, some as German/Scandinavian? To add confusion there's Italian white Moondancer and Italian yellow Moondancer.
I've never been entirely sure how and where she exists, but she's pretty nonetheless.
-UK/Euro 'Wedding Bells' Confetti is in the Bow Tie pose, whilst US rainbow pony Confetti is in the Posey pose.
-Kiss Curl, who came with the UK BMB Boutique playset, has two symbol versions. The regular symbol has pink hair tied with blue ribbons, the reversed symbol has blue hair tied with pink ribbons. Reverse symbol is harder to find, I believe.
-SS Magic Star is in the rearing Truly pose, whilst NSS Magic Star is in the Tootsie pose.
-SS Buttons comes with three large buttons on her symbol, whilst there are two versions of NSS Buttons - one with three large buttons, and one with six small buttons and blue stars.
-Gusty and Posey, which had normal releases in 1984, and then SS/NSS releases in 1985 or later, have some small variations between the normal release and the NSS release. Regular Posey has pale tulips, NSS Posey has dark magenta tulips (she's already on your list, I see
). Regular Gusty has glittery symbols and blue eyes, NSS Gusty has painted symbols and green eyes.
-Babies Lickety-Split, Gusty, Ribbon, and Heart Throb - released in the US as BBE babies, and in the UK/Europe as NBBE Play and Care sets.
-NBBE Baby Heart Throb has two variants - one with wings on her heart symbols, and one with no wings.
-Babies Cuddles and Tiddley Winks first released in 1984 as NBBE with their playsets, later BBE versions rereleased in 1985 with their playsets.
-NBBE Baby Cuddles may have two variants - one with freckles and one without freckles?
-Baby Half-Note was released with their playset in 1985 in both BBE and NBBE versions.
