1985: Rainbow Ponies
PINWHEEL
Dark pink unicorn pony with melon/pink/blue/neon yellow mane and tail, glittering pinwheels symbol
For some odd reason, Pinwheel made an appearance in the UK fact File with no horn, despite her snippet being about unicorn magic. Pinwheel, I remember, used her particular rainbow mane magic to make little pinwheels appear (much to the delight of elves, pixies and baby ponies!). Whether this magic of hers was down to her being a unicorn or a Rainbow Pony seems largely up to the reader :S
Pinwheel was never sold in the UK - sadly, despite her comic appearances.
