Mr. and Mrs. Cake give birth to a pair of twins: Pound Cake, a pegasus, and Pumpkin Cake, a unicorn. A month after their birth, the Cakes are forced to ask Pinkie Pie to babysit the twins while they cater an event. Pinkie, initially happy to be able to play with the babies, finds that they are much more difficult to tend to, but she refuses to accept Twilight's help, believing she can show responsibility. However, when the twins later exhibit their flying and magic abilities, Pinkie can no longer control them and breaks down in tears. The twins realize their mistake and cheers Pinkie up. Mr. and Mrs. Cake return to find everything is fine, and offer Pinkie to be their go-to babysitter in the future, which Pinkie accepts after hearing the twins say her name.
