Karyn held the stone close to her breast and said, "I wish Jon would blend in more until we get home." A slight breeze ruffled the skirts of their dresses.
After the glow from the stone dissipated, Karyn saw that Jon was gone and in his place was a toilet! Jon had turned into a toilet!
"No, no, no," Karyn said. "I didn't mean blend in more with the restroom."
She started to get worried. "How am I gonna fix this?" But then she remembered the words of her wish. She ended it with 'until we get home'. All she needed to do was get Jon "the toilet" home and he'll change back to normal.
