The Baby Rainbow Ponies were printed in Year 9, between 1990 and 1991. They resemble both the previous year's Rainbow Curl set and the much earlier Year 2 Rainbow Ponies and Year 3 Rainbow Ponies. Their hair is striped with three colors (rather than four like all of the adult Rainbow Ponies). Their symbols are smaller than Rainbow Curl Ponies' symbols, but more complex than early Rainbow Pony symbols (and are printed in paint, not glitter). Each Baby Rainbow Pony came with a flower brush.
