Unicorn Kiss part 3

"Who are you?" Frella inquired. The giggling stopped and a short while later a rather small pixie the size of her thumb appeared before her eyes! "Oh!?" Frella said with a start she hadn't realized the pixie was even there until it had flicked her upon the nose. Then the pixie drew her attention to the waffle sized ruby. "Yes. Yes," she said to the pixie, "It's a very beautiful ruby." The pixie laughed then mimed something Frella didn't understand. The pixie drew in her arms and flew in a squating position, and then it dawned on Frella what this pixie was miming, and it also explained the wierd coating over the jewels she had picked up most recently. These little thumb sized pixies pooped jewels!
