1990: Rainbow Curl Ponies
RAINBOW CLOUD
White earth pony with pale pink, yellow, lavender and aqua ringlets, cloud with rainbow spread across sides and purple stars symbol.
Rainbow Cloud was the first Rainbow Curl pony to be introduced into the comic, when Caramel Crunch and Sugar Sweet took a trek into the mountains and discovered a world full of rainbows.
Rainbow Cloud's special magic - as her name suggests - involved clouds and the fact that, when she wiggled her nose at one - 'anything can happen'. In this particular instance, it rained rainbow popcorn - but whether she or the Candy Canes did it is still open to debate ;)
She was called Raincurl in the North American release.
The pale pink ringlet in her hair can fade to white in sunlight (this isn't a variation) and she can lose her curls quite easily, especially if groomed when wet.
