As Jim strolled around the food court in the mall, he saw a short, skinny kid standing in line at one of the fast food places. The boy was wearing flip flops, shorts, and a basketball jersey. Jim could tell that the kid was skinny as a board, and had very little muscle. He was very short and scawny, and Jim guessed that he often got picked on in school.
"I bet he could use some muscle..." Jim chuckled to himself. Jim guessed that the boy was about 4 foot 9 inches tall, and he was skinny to the bone. He took the balloon in his fingers and spoke the magic words.
"Control the size of the skinny boy's muscles all at once and in proportion!" Jim commanded, just before he placed the balloon's spout between his lips. He then inhaled deeply through his nose, before allowing the air to blow through his lips into the balloon through the spout.
"FFFOOOOOOOOOOFFFF!!" was the sound that the balloon made, as it inflated into a little, round sphere.
Suddenly, the skinny boy gasped, as every muscle in his body started to grow, all at the same time, and all at once! His quads grew thicker by a few inches, as well as his calves, which became thicker and more round. His chest pushed out further while his arms suddenly grew twice as thick as they were before! His shoulders widened as well! Suddenly, the skinny boy resembled a young member of the swim team!
"What? What the heck?" the kid wondered, as he looked down and examined his body, following the sudden growth spurt. He delighted in the sight of his increased biceps, and flexed happily as he admired his new muscles.
"One more time..." Jim thought, as he inhaled again, and blew some more air into the balloon. The balloon grew twice as big this time!
"FFFFOOOOOOOOOOOOOOOOOOOFFFFFFFF!" it sounded, as it expanded with more air. Jim then removed the balloon from his lips.
"Release" Jim said quietly.
In the meantime, the boy was suddenly overcome by a second sudden growth spurt! His muscles expanded again! This time, he was almost turning into a gymnast, right before his very own eyes! In fact, he was a junior bodybuilder!
His quads and calves inflated even more, becoming rock solid. They were huge! His abs were like plates of steel, and his chest consisted of two large spheres of muscle. The boy had suddenly gained 30 pounds of muscle! His arms were like pythons of power, and his shoulders were twice as wide as before. His shirt was almost at the point of ripping apart! In fact, it had already begun to tear at the collar! His legs had grown so thick, that his shorts had begun to tear at teh seams as well. Luckily Jim hadn't made him any bigger than that.
"I need to buy bigger clothes!" the boy said. Immediately he turned around and started looking for his mother. He would have to explain that he had a sudden growth spurt, and needed bigger clothes. Luckily he was already in the mall...
"Another new muscle boy..." Jim chuckled, as he watched the young muscle boy running down the corridors of the crowded shopping mall.
Who would he grow next?
