The Jack-in-the-Box is a large toy encased in a brown musicbox with pink diamond-shaped markings on it. When out of it, he resembles a jester with pointed edges. His head has brown hair and a beard, along with a purple-and-blue-hat with two points, each having a bell at the end. Underneath the hat, he is bald. His face has a long nose and pink cheeks. His head takes up the majority of his coily body, while his arms are smaller in comparison. He wears a blue collar with golden edges to complete his outfit. Due to the box acting as the lower portion of his body, he can only hop around as mobility.
