Andrew entered the second chamber. As he entered the door closed again and there was another door opposing it.
Suddenly a blue glow emerged from the ceiling, completely surrounding him. He found himself paralyced, unable to move even the slightest bit, has the beam was working on him, he eventually passed out.
Waking up again, he found himself lying on the floor. Opening his eyes, he noticed that his nose became considerably longer. In fact he had a whole muzzle, looking at himself he found that he was now an anthromorphic opposum. Feeling down with his fairly hand-like paws, he noticed his sheath with his biforked member poking out of a bit. His tail was fairly strong and agile. He couldn't believe what has happened to him. Was he beeing drugged? Was he dreaming? As he didn't feel any pain or had any other option, he tried exploring his body a bit. He quickly grew to like stroking his sheath and tail. The exploration of his body was stopped by the next door opening, going to the next room.
