Ty tried to move his arms, but found that he couldn't. They were just too large. As impressive as they were, the 35 inch guns Ty now possessed prevented him from having full range of motion.
Also, after looking at himself in the mirror again, he thought he was too...massive. I mean, the muscle growth was good, but what good would it do if he couldn't enjoy it? He was just like a big blob of muscle now.
"I wish I could grow tall enough to have good range of motion." Suddenly, he began inching upward, his 400 pound body eventually filling out quite nicely.
As Ty reached the 6'7" mark, the growth stopped. Ty looked himself over, relieved he could move his limbs once more. He flexed one of his massive arms, astounded at the overall size of the biceps and triceps.
Ty realized he still had a ways to go before his head reached the ceiling of his room. This gave him an idea.
He then wished himself to be 7 feet, 2 inches tall. His body responded to his command. Next, he added another 100 pounds of muscle onto his frame. Ty watched in amusement as his frame filled out once more.
To top it all off, he then wished that everyone, except for Dustin, would think that Ty had simply grown into the body he had now. Every relative, every friend, every teacher at school and anyone Ty might had met along the way, now received that knowledge.
Ty glanced over at his closet, glad that his clothes looked large enough to fit his massive frame now. He walked over to his much larger bed and laid down, wondering how his older brother would react at seeing him the next morning...
