You hit the button of a green dragon.
You feel the changes instantly, your ears disappear, and a white nub falls out.
So much for the tracker.
Your body starts changing as 2 fingers merge into 1 and your thumbs migrate to the back of your wrists, the creeeeak and snap of your bones as they get into place is scary. Your skin toughens as green scales slide over the surface of your body and your hair falls out. Your fingernails slide off and are replaced with long, sharp claws. Your fingers grow slender, and your teeth sharpen and lengthen. And your tounge splits as your head grows out from the mouth and nose. Slits form where your nostrils were. Horns sprout from the back of your head as a tail erupts from behind you. Ripping your pants off. You don't notice because your body is already growing.
Your body expands and your shirt rips off your chest. The muscles on your arms and legs triple in size and they lengthen outward. Your neck c-r-e-a-k-s as it lengthens. Your body soon fills the room, the walls protesting. Then they crumble.
You feel as if this transformation is not over yet. Ah, yes, your dick.
