Sofia the First: The Wishing Amethyst

This story is pretty similar to "When You Wish Upon a Gemstone."

Sofia's best friend, Prince Hugo, has come to sleep over for two weeks. When Ruby and Jade come to see Sofia, they become jealous of Hugo because she's busy training him on the obstacle course. When Jade and Ruby try their best to get her to spend time with them, they find a magical amethyst in the berry patch, and it grants wishes. The girls want Sofia to spend time with them so badly that they wish on the amethyst that she was allergic to Hugo. But the wish backfires, making Hugo smell like Amber's fancy new perfume. Since the smell is enchanted, it won't come off! When Ruby and Jade realize the mess they'd made, they try to fix it only to make it worse. Should the girls come clean and fix the mess they made? Or should they hide their responsibility from Sofia and Hugo?
