1990: Tropical Ponies
Hot dark neon pink earth pony with orange, dark neon pink and blue mane and tail, blue and gold palm trees swaying symbol.
And this is Hula Hula, the palm tree dancer and the true Hawaiian among the set in that sense, I guess ;) Well, the grass skirt thing might be a bit cliche, but somehow it fits her down to the ground! In the comics, she would live up to her name and she is even mentioned on Sail Away's backcard for dancing under palm trees.
In the North American release she was called Pina Colada - which is, admittedly, a pretty neat name, if a touch alcoholic ;)
My sister had this pony new as a child and I vividly remember that she came with an electric blue fish comb (because I kept nabbing it!)
