Sweetie is a little three-year-old girl who loves swimming... in her pajamas! She always wears a pink pajama onesie decorated with bright red hearts, a pair of pink mittens, a pair of purple slippers with red hearts on them, a lavender nightcap, a fuchsia eye-mask and a pair of violet swimming goggles that she's superglued onto her eyes. She lives in a very sweet little neighborhood with her four friends and five sisters, all of whom love swimming in their pajamas just as her.
