My Little Pony - Baby Rainribbon (1990)

One cloudy day, the Rainbow Babies were bored with their nursery toys. Gazing out the window, they saw the rainbow trying to break through the clouds. "Let's make a rainbow they shouted. They scampered outside with all their hair ribbons and began to tie them together to make long colorful stripes. When they were finished, it looked like a rainbow indeed-but it was on the grass, not in the sky where rainbows should be. The ponies touched the stripes with their noses...and the ribbons turned into a real rainbow and floated up in the air. "Now we have a double rainbow!" laughed the Rainbow Baby, as everyone came outside to admire the ponies' beautiful creation.
