Apple Bloom has a sister, Sweetie Belle has a sister, and heck, even Scootaloo got one recently. So why should Diamond Tiara be the filly without one? In fact, hers should be ten times better than all of theirs combined! And with her father being the richest stallion in Ponyville, she should have no trouble getting one!

... That is if he wasn't such a stingy, mean father. Thankfully Diamond Tiara's a smart filly and knows how to get what she wants.
