Set a few years into the future, six year old Pound and Pumpkin have a lot of growing up to do. They fight and make up, make mistakes and learn lessons, and love and protect each other as much as they get on each other's nerves.
Pound and Pumpkin Cake agree to look after Lil' Cheese for Pinkie Pie so that she can have a much needed break. Of course, Lil Cheese is anything but cooperative. He's intent to give his new foalsitters a hard time. Will he break them?
Pumpkin Cake looses the Spike plushie she got from the Crystal Empire. While looking for a replacement, the real Spike walks in. Pumpkin then proceeds to follow him around for the rest of the day
When Pinkie falls ill, Rarity takes her place as a foalsitter for The Cake Twins, and they take a real shine her to. This makes Pinkie feel like she's been replaced, and it's up Mr. and Mrs. Cake to show her that's not true.
