When Karyn said "jump", Jon immediately thought of one of his favorite animals.... And as soon as he thought of that, that's exactly what he wanted Karyn to be!
Suddenly Karyn's sentance was cut off as she began to change form. "Jon! What have you done this time!"
As Karyn began to sprout grey fur from her arms and face, her face lengthened and her fingernails became black, becoming like claws. Her clothes then began to fade away and the lighter fur on her belly was revealed. Finally, a tail sprouted from her backside, her feet began to change shape, and her legs became thick and powerful.
"Jon, what have you turned me into this time!" Karyn said, looking herself over. As she tried to turn around to look at her tail, she began to stumble and ended up taking a large hop forward.
"Jon... you... you... turned me into a kangaroo!"
Jon smiled at her. "You look good this way Karyn. I think I'll keep you this way for a while. No skunk spray in this form, no sirree!" he said, chuckling.
"Jonathan, I'm going to get you back for this!" Karyn said, leaping toward him. Jon backpedaled to get out of her way.
"Naughty naughty roo! You're not going to get the stone that easi... OOF!", Jon said, as he suddenly tripped over a root he didn't see while backing away from Karyn.
Jon lay sprawled on the ground, and sat up, holding his back as he did so.
"Oww... Karyn...", he began to say, but was cut short when he saw a blur of grey fur bounding toward him quickly. Then, just as KAryn was about to collide with him, she took a great leap over his head! As she did this, Jon quickly lay back on the ground trying to avoid being struck by her.
"Woah! Be careful Karyn!" he said, turning around. When he did so, he saw Karyn land a good 10 feet behind him, and bend over... to pick something shiny up off the ground. Frantically Jon looked around him for what he knew wasn't there... Karyn had gotten ahold of the stone which had been knocked out of his hands when he tripped over the root!
Jon heard Karn mutter something, and then say "It's not working!"
"You tried to wish yourself back to normal, didn't you. That would work, except for the fact that I wished earlier that you'd only be what I wanted you to be! And right now, I think this form suits you best.", Jon said, with a smirk.
"Oh yoooooouuu!!!" Karyn said angrily. "Fine then... instead I'll wish..."
