"I wish it was a necklace," Karyn giggled. Suddenly, the stone glowed brightly, causing all three girls to look away momentarily. "Oooh! It's so pretty! How does it do that?" The three girls watched as the stone morphed into the shape of a necklace, one that was made of the same material as the stone. Karyn immediately put it on, seeing how it looked on her. Apparently, she liked what she saw. She giggled, then said "I wish I would never take it off."
"No, you moron!" Sarah yelled.
The necklace glowed, granting Karyn's wish. Now anything she wished would come true, since the necklace would always be touching her skin. And given Karyn's limited intelligence, her wishes wouldn't be very thought out.
