This My Little Pony t-shirt shows the popular unicorns Windy and Moonstone underneath a rainbow. The shirt reads Friendship. 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.
