"Both" replied Matt.
Jen was shocked. "Really? Why?"
"To prove I'm on your side."
Jen thought for a moment, figuring out what to do. She wasn't sure how to get revenge on Kyle yet, but she had some ideas. In the meantime, she could start by showing Kyle not all of his supposed friends were really on his side while not feeling quite as isolated by her changed appearance. She might even have some fun.
"Okay, I've got it. For your transformation you will have frog-like webbed hands and feet like I do. You'll also be able to extend your tongue like a frog, although your tongue will still fit comfortably in your mouth and not affect your talking. You can't use the curse to undo these changes, but you will return to normal once I'm satisfied with my revenge against Kyle."
Matt quickly removed his shoes and socks in preparation for the change. A moment later, he watched his toes extend and develop webbing then watched the same thing happen to his fingers. Like Jen, he now had hands and feet like a frog, but with normal skin color. Then his mouth started to feel funny and, almost instinctively, his tongue shot out from his mouth then pulled back in. He shifted his jaw around, but while his mouth still felt a little funny it was not uncomfortable. Experimenting, he slowly let his tongue out then used it to touch the end of his nose then his chin. He let it hang there for a moment and made a goofy face like he was Gene Simmons from KISS.
"Okay, Jen, I get the hands and feet so I'll be like you. But why the tongue?"
"Because of the dare, silly."
