He started to shrink!
Charlie sat on the river bank, in his blue and green-striped old-timey bathing suit, with his toes wriggling and flexing like worms.
Slowly, but surely, he began to feel himself getting smaller.
"Holy cow." Charlie muttered to himself. "I'm shrinkin' outta my bathing suit!"
Indeed. His blue and green-striped old-timey bathing suit wasn't shrinking with him - it was gettin' looser on his shrinking body.
"Oh, er, oooh my." Charlie said as he sat on his towel and became more smaller.
He became smaller and smaller and smaller and smaller and smaller and smaller and smaller and smaller and smaller and smaller and smaller and smaller and smaller and smaller and smaller and smaller and smaller than usual.
Charlie sat and wondered how small he was going to be after this.
