This My Little Pony t-shirt shows Windy and Moonstone under the colorful My Little Pony rainbow logo. Windy is the fastest of all the rainbow ponies. She wins all of the Rainbow Races held at the Dream Castle, always leaving behind a rainbow of light. Moonstone is always looking for rainbows. When she finds them, she gets so excited that different colors come shooting out of her mane and tail like fireworks.
