Kyle said, "Okay. Calm down, and listen to me. I'm not going to chose because I want you to use both. Dare me to act like I did before my grandma cursed me, and transform me to be that way too."
Jen grinned with her beaver teeth. "Might turn you into a baby, you know. And I wouldn't want a baby in charge of cursing me." She thought. "I think I know what you want though." She waited until a minute had passed and the curse hit Kyle with both barrels. "Okay, you said you used to be a popular football player? Alright, here's what you get: I want you to transform into whatever would be appropriate for whatever team you're on, and I dare you to be really nice and friendly and ingratiating. We're talking school spirit to the max. Got that?"
Kyle nodded, and then his horns began to grow longer and more twisted, his goat mouth sprouted savage fangs, huge bat wings unfurled from his back, a long barbed tail sprouted from his behind, but he still kept the cloven hooves and fur, except the fur turned electric blue. Kyle gazed at himself in horror, then started to smile in wonderment. "Cool! I've become the school mascot! I'm a Blue Demon!" He turned to Jen with a friendly leer. "Are you going to the pep rally? Oh, of course you are! You're a cheerleader!"
"A pep rally?" gasped Jen eagerly, but then patted the ground with her fat tail. "But I'm still a beaver girl! Please, transform me back!"
Kyle smiled the smile of a happy ingratiating school mascot demon. "Of course! Transform or Dare?"
