Jack is a small creature, of Irish origin, known for it's easily disrupted temper and compulsive lying. Jack's love to make threats that they well never deliver, not only this, but they get all up in people's faces when they are challenged, clicking their fingers as they do so, to try and seem larger then they really are. Most Jack's are pessimists, always attention seeking when a problem occurs.
