The Lightning Kid had once had his hair cut by his own grandmother... it was essentially a bowl cut. While some found this more objectionable than others, the King and Queen were willing to tolerate it ... for a while. Still, the hair continued to grow (as hair is prone to doing), and the Queen was becoming decreasingly tolerant of those who referred to the Lightning Kid as a princess rather than a prince upon first laying eyes upon him.
So she took him to the business that had done a good job of Shark Boy's first haircuts... and so the Lightning Kid turned from a baby, to a handsome looking little boy!
It was a bittersweet moment for the King and Queen; they were pleased with how good he looked, but the idea of him not being a baby anymore was saddening. Then a greater worry occurred to them: without long hair standing on end, would he still have his Lightning?
Later that day, the Queen took him to a private chamber for nursing, and rather than settle down for the feeding, the young prince would not stop looking around and trying to interact with the other children. Pretty soon, none of the mothers were able to peacefully feed their children and were forced to leave because the children all wanted to watch the Lightning Kid. It seemed like the Lightning Kid hadn't lost his thunder!
