The twins are on the train ride to visit Pinkie Pie's sisters and parents, which she calls their aunts and uncle. Pinkie is excited, but the twins aren't so sure because a.) They don't even know what these ponies are like, b.) they have been put back into diapers for the train ride, and c.) Pound has heard a rumour that rock farmers don't use bathrooms (and don't even put their babies into diapers). Pumpkin is pretty sure that rumour is not true, since Pinkie Pie can use the toilet and she thinks it'd be pretty odd if she was potty trained by herself or Mr. and Mrs. Cake. The twins decide that there might be an outhouse, but find the idea a bit gross.
They depart the train, get changed back into pull-ups, and ride in a foal carrier on Pinkie Pie's back to the farm. When they get there, they meet the rest of the Pie family, who initially think the twins belong to her, but she explains they don't.
They go inside and Cloudy makes some rock soup, Igneous sits in his chair, and the Pie sisters play with the twins. Pound asks Igneous for "uppies" and then flies away with Igneous in pursuit. Pumpkin levitates herself and flies away too, then more of the sisters give chase and Pinkie Pie tells them off, intimidating them into submission. Then, they go to eat rock soup.
