Dave drank from the small bowl from the fountain of size.
He then lay down near the fountain for a snooze.
But.
As he was sleeping, he started to shrink!
His clothes began to loosen, and he could feel his feet knocking around in his boots.
He had failed to take into account that the effects of fountain’s water had no effect on clothing.
Dave awoke, and saw to his surprise that the water in the fountain of size had worked. He saw that he was standing on his now oversized coat. His emptied clothes spread haphazardly over the Lawn.
"Wow! It worked!" he said, wriggling his toes in amusement and glee. "I'm really small!"
And he noticed he was naked. His clothes hadn’t shrunk with him, not even his underwear.
He was now the size of a toy.
