Jimmy stretched his young arms. When it came down to it he wasn't sure he really wanted to change back to his normal age. The energy of childhood was contagious and addicting. With mere thoughts his clothes were all smaller to fit him, though he had to wear his jeans slightly low to allow for his extra size down there.
Quickly he rushed to the bathroom and stood in front of the mirror. Jimmy quickly pulled off his shirt and stood there in only boxers, with a large bulge in front. He gazed at his thin, perfectly tanned frame and snapped his fingers. Jimmy's frame filled out a little with muscle. Not too much muscle, but enough to make him look like a little gymnast. A fairly solid six pack showed and his pecs bulged out a little, along with his other muscles.
When it was done he was no longer skinny, now he was a leanly muscular young boy and he added a little something extra to himself. He had created an 'aura' of sorts that made his looks irresistable to anyone looking at him. Kids younger than him would want to be his friend and look up to him, while adults would think him the most adorable kid ever. That considered he snapped his fingers and knowledge flooded his head. Now he was both a child actor, and child model. Loving the feel of knowledge he flooded his head with knowledge until he was easily a genius. He was only nine, but he attended university because of his incredible mind.
Those changes done he pulled back on a t-shirt and jeans, and grabbed his skateboard; that is he grabbed his newly created skateboard, and with no effort at all he teleported across several blocks to the skate park.
