Jackie is an animatronic based heavily on a jack-in-the-box, taking on the appearance of a birthday clown. Jackie has a white painted face, with red eyebrows, red lipstick, which goes up to her cheeks, and blue eyeliner. Her eyelashes are painted on both sides, each having two red lashes and one blue lash. Jackie has large, green eyes, and a big red nose.

Jackie's body adorns a white pintuck shirt tucked into a blue hem, and she wears a large red bowtie with three red cotton balls underneath.
