1983:Unicorn and Pegasus Ponies
MOONDANCER
White unicorn with dark red hair (lavender streak in mane) and glittering red stars and silver moon symbol
Moondancer is often said to be the only pony with her peculiarly claret colour of hair. Though one of the Dutch ponies - Snoepjes - has a very similar shade, it does beg the question of WHY.
Moondancer's hair makes her one of the prettiest ponies from that release, and is possibly the reasoning behind her re-release with the second set of Unicorn and Pegasus ponies the following year. But the red colour was never again used for a mainstream pony, and you have to imagine that Hasbro were unable to properly reproduce it's colour properties (either that or the process was expensive). Not even Moondancer's own baby had the red hair!
In terms of personality, Moondancer was mischievous and playful. Her backcard story (USA) talks about her putting Cotton Candy into a deep sleep for eating too many flowers, and she was often off exploring in the pony comics, too. She also had the ability to light darkness with her horn - a trait she often used when treasure hunting with her fellows!
In parts of continental Europe (namely Scandinavia) there exists a yellow version of Moondancer. What her story is is unclear, and though she was sold on a UK style of card with a set including Powder and Skyflier, she was definitely never sold in the United Kingdom.
