Dan's skin was tingling. He felt a sudden jolt, and then he opened his eyes.
His skin seemed to be covered in smooth green/grey scales. He jumped up in horror, trying to scratch them off. Of course, it didn't work; this was Kat's magic.
So the inner animal inside him was some sort of lizard... or maybe fish... or maybe a dinosaur! But even the childish thoughts of becoming a dinosaur didn't justify the removal of his humanity.
Dan went for the door, just as another change came on.
