In 2008, they released the "Original 1984 My LIttle Pony Collection" as part of the 25th anniversary celebration. There were two sets of two repro's released; the first was Earth ponies, the second was Rainbow ponies. PArasol, Moonstone and Starshine were in one rainbow set, and SUnlight, Windy and Skydancer were in another, so it looks like you got two from one set and one from another (rainbows).
