"Change into your old guy self, Alison."
Nothing happened.
"It didn't work," said Alison. "I guess this isn't enough. We need to change more before the stone thinks that we already reversed the wish."
"Yeah, tell me about it," said Joy.
"We need to change more before the stone thinks that we already reversed the wish."
"I didn't mean to really tell me!" responded Joy. "We just need to change some more. I'm sure we could come up with something better. Like painting our nails. Or trying to talk in a more girly voice. You sound like a guy pretending to be a girl. Hmm... I'm going to try something first... Tell me what we need to do."
"Nothing."
"What? How's that possible, Alison?" asked Joy.
"I don't know," replied Alison. "You asked me to tell you so I told you."
"All right, tell me how it's possible."
"We don't look like we did back then. So the part of the wish saying that we look like we did back then is already reversed. But the wish made us girls who look like we did back then. The "girls" part isn't reversed and we can't reverse it ourselves. So we can change ourselves again using orders or wishes, but only into girls."
"What about the disguises?"
"I don't know."
"Tell me."
"The disguises became real and we can't reverse that either, but disguises can be worn by people of different body shape. There's a limit to how small we can make our breasts and hips, though."
"What?" said Joy. "This is going to be a problem. I don't want to be any kind of girl and I'm sure you don't either. What are we going to do?"
"Let me think of a wish," said Alison, looking at the new stone and thinking.
