I really really thought Holder's Boulder was an egg at first and it was gonna hatch.

I really wonder about the Pie girls. Maude is the oldest as far as I know. The wiki entries on Maude and Limestone both say they're the oldest. When we first saw Limestone and Marble they were side by side and the same size so I really thought they were twins. But Pinkie said Marble is a few minutes younger than her, making them twins. Or are they triplets?
