Jon and Karyn sat down on Jon's bed after walking home from school. Karyn had a rough day adjusting to her new attributes. Jon had been making jokes at her expense all day. She'd been getting annoyed all day. When they got to Jon's house she wanted to relax and have a bit of fun.
"Where's the stone at?" Karyn asked. "I've got a fun idea for a wish."
"Oh yeah what is it." Jon said.
"Nah ah, not until you give me the stone. It's a game." Karyn said.
Jon sighed and reached under his bed for the stone. "I know I know, real secure, I didn't know where else to put it. Here you go, what's the big surprise."
"Well, since you've been making fun of me all day I thought we should have a contest. We each wish a change to the other person. We make sure to include some kind of clues to the wish. The first person to figure out their change reverts back, the other person keeps it. We do one change a day and afterwards everything goes back to normal."
"Umm, sure." Said Jon. "I guess that's fun. So we pick something each day, how do we know who figured it out first."
"It's a magic stone Jon it can figure out when we know. Come on it'll be fun." Karyn paused "I wish we had a box with materials to play the game I've just described."
They both looked away when they looked on the bed an ornate wooden box sat on the bed. They opened the box, inside was parchment to write the change on, there were two booklets. One for each person.
"Alright, round 1" Said Jon.
