Neptune and Uranus where just talking happily, when suddenly, a dark blue planet they don't know walks up to them. Uranus gets scared, and hides behind Neptune, while Neptune raises an eyebrow "Who are you?" Neptune asks "You don't remember me..? Tch, of course Jupiter and Saturn made you not remember.. I'm a Planet X, but you two.. can call me big brother"
