"What do you want for your birthday, Luna?"

"A puppy!"

It's been 1010 years since Luna asked for a puppy. And now she finally got one.

It's a wild Border Collie. One that doesn't know how to act like a royal pet. One that pees indoors and eats the cushions.

Will Luna and Celestia be able to handle this rascal? When hope seems lost, the two look to Fluttershy. But not even she can help. Yet she knows someone who can. Make that someones.
