...make the clothes grow.
So that his dad didn't see or hear him, he went upstairs into his room.
"Control the size of my dad's clothes," Jim whispered.
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's Clothes started to grow.
yes, that's right - ALL of them.
his brown shoes, blue socks, as well as hisblack slacks, and his white shirt and green tank top. and yes, even his boxer shorts in his slacks would grow too.
They grew bigger, and bigger, and bigger, and bigger still.
But since Ron's body stayed the same size, they became much too big for him to wear.
Ron's shoes fell off his feet. Jim gapsed, as he heard Ron splutter in his sleep, fearing his dad would wake up. but he didn't. Though, Jim did hear his dad murmur in his sleep, "I wanna ride the pony..." before drifting off again.
Jim released the balloon, and then, he checked his dad's clothes were still enormous. They were.
