After his place appeared, Nick clicked on his avatar. Immediately some basic stats popped up regarding his height and weight, as well as a More button. Nick entered the weight box and changed the weight from 210lbs to 160lbs. He wanted to be less fat. He pressed Save Changes and felt a tingle along his body.
Suddenly, Nick's body seemed to start shrinking. His stomach sucked into itself, his arms and legs thinned out slightly, and he became less bulky in general. After a couple moments, Nick stood as a still-slightly-pudgy-but-much-better 5'2" boy. But that was about to change. Nick then clicked on the height box and changed it from 5'2" to 6'2". As an afterthought, he also upped the weight back to 210lbs. Nick pressed Save Changes again.
Immediately Nick felt a new sensation. His legs thickened with the extra weight, growing longer and longer. His body lengthened more and more. Even with the added weight, he was still thin for his height. Nick's shorts were almost thigh highs now, they barely covered anything. As the sensation ended, Nick stood there as an extremely tall and thin boy.
