"It is so hard to find a sitter with a sense of humor for Lil' Cheese." Pinkie never imagined just how much those words would come back to haunt her, but now they have. Called to Canterlot for the annual Council of Friendship meeting, she must leave her son behind.

As luck would have it, Cheese Sandwich is also unavailable to foalsit, as his "Cheesie Sense" is calling him back to Manehattan to plan a birthday party for one of his relatives. So now he and his wife have to find a foalsitter on short notice.

To the relief of both parents, a candidate soon steps forward despite her lack of experience in dealing with Lil' Cheese: Diamond Tiara. Can Diamond Tiara break the curse that has plagued so many other foalsitters for the child of Pinkie and Cheese? Or will Lil' Cheese prove to be too much even for her?
