Magic Mucus: Jon Figures It Out

Jon frantically looked around the room. *Why aren't there any tissues around when you need them?* he thought, before his eyes landed on the paper towel dispenser. *Good enough.* He jumped up and grabbed a paper towel, catching his sneeze in time. Then, suddenly, the paper towel began to change right in his hands. When it stopped morphing, it became a box of tissues. "How the hell are you doing that?!" asked the "new" Karyn, who still had the mind of the boy she used to be. "I ... I think when I sneeze on something, it changes." But why did the boy become Karyn and the paper towel become a box of tissues? He thought for a moment and realized that the boy and the paper towel became whatever he was thinking of at the time. Now he definitely needed to tell Karyn what was going on.
