"What is it?" asked Katheryn.
"Turn Sarah into a guy who's just pretending to be a girl. Get her disqualified as a cheerleader, one of us can be one instead."
"Okay, I wish Sarah was a feminine-looking guy, without changing her memories or personality." Nothing happened.
"You can't reverse the wish about being a cow," said Jon.
"Oh! Hmm. I wish that Sarah was a fat cow, but isn't any longer. And I wish I can change anything I wished, so I don't have to keep worrying about this kind of thing."
Sarah changed back, and was lying on the ground with arms and legs in a four legs position. She pulled herself to her feet, but then had to cover herself because her clothes were still shredded.
"I wish," said Katheryn, "that Sarah is a guy who's pretending to be a girl, and that she's convincing but will be discovered tomorrow and kicked off the cheerleading team for it."
