He decided to make his dad's white shirt in a green tank top bigger.
Like before, he went into his bedroom, and whispered, "control the size of my dad's shirt and tank top."
He then took a deep breath, blew into the balloon and it expanded with a “FFOOOOOFFF” and the sound of stretching rubber. At the same time, Ron seemed to have his shirt and tank top getting bigger.
it became as big as a blanket, and his dad almost looked at if he was covered by a massive shirt and tank top.
Feeling reckless, Jim blew into the balloon again, but much harder. It expanded with a FFOOOOOOOOOFFF.
Rom's shirt and tank top got bigger and bigger. So big, in fact, it completely almost covered his whole body.
Jim was amazed when he saw it. he was excited to grow something else, including another item of his dad's clothes.
He released the air from the balloon a second time, and, after a check to see if his dad's shirt and tank top was still big, he decided to make it even more amazing, by enlarging another item of clothing.
