Pinkie Pie wants to see her sisters again, so she brought all of her friends and their sisters along with her, plus Thunderlane and his group. Even Trixie and Lightning Dust came along for some fun.

But as they would know, Pinkie's sisters aren't exactly like her, how will they handle an unfriendly Limestone, who has something she doesn't like about them, a really shy Marble that even Fluttershy's impressed at, and the usually quiet but suddenly awkward Maud?

Things are gonna get a little more interesting.
