A Unicorn Named Sparkle by Amy Young
When Lucy sees an ad in the newspaper for a unicorn, she sends in her twenty-five cents and waits four to six long weeks for her very own unicorn to arrive. She imagines the flowers that she'll braid into his beautiful pink mane, and she even picks the perfect name for him: Sparkle. But when Sparkle arrives, his ears are too long, his horn is too short, he smells funny - and oh, he has fleas. Lucy isn't pleased, but in the end she warms up to Sparkle and realizes that even though he wasn't exactly the unicorn she wanted, he might be just the one she needs.
