When Mike is in an opening in the forest, he takes a brake and rests on some rocks.
A little while later, he wakes up, feeling burning on his sides. He took off his shirt, figuring he was too hot from laying in the sun for so long, but by then, he feels burning all over himself, and he notices scales forming on his body. He freaks out so much, that he passes out, and when he is asleep, he grew a muzzle, a tail, and wings.
When he finally wakes up, he sees he is half human/half dragon, with black scales, and blue scales on his chest, belly, and bottom of his tail.
After staying out for a night, not wanting to go back to camp, he realizes he has the ability to change from dragon form to human for and back, so he goes back to camp once he has figured out how to make himself stay human.
