US Backcard Story
A beautiful butterfly floated past Primrose while she strolled to the Castle. She raced after it, admiring its pretty colors and delicate wings. It floated over hills and through fields, causing Primrose to run in a wavy line trying to keep up. At last, it stopped in the garden to rest. Primrose sat nearby, watching the butterfly dance from flower to flower to find the softest petal. Then Primrose heard someone calling her name. "Here you are!" exclaimed Princess Sparkle. "You were supposed to help me decorate the Castle." The two ponies skipped back to the Castle with their lovely new friend leading the way.

UK Backcard Story
Princess Ruby can never make up her mind just what she wants to do next. In fact, she is so undecided that she never has the time to finish one thing before she starts the next. Her dragon, Sparks, spends all of his time following her around and finishing off the tasks which she has left uncompleted.
