Just as he thought that, the feelings kept getting weirder and weirder. What he felt next he couldn't describe in words other than he just grew another leg/hand... or a tail. The meaty appendage fell heavily to the floor from his pants, dragging him back as Dan started to loose balance, completely confused in what he had to move and how. Nor did it help that his leg bones cracked and he lost support, falling helplessly to the floor as he watched his soles grow and elongate, and his calves shrank and buldged, deforming his body until it started to resemble more reptile than human. Dan tried to move his legs in a bit of a shock, partially expecting them not to be his, but the claws lifted and dropped as his toes would, which freaked Dan a little.
Dazed and a little shaken, he made an attempt to stand up. As he stumbled back on his feet, he found himself naturally taking a somewhat feral stance with his heels not touching the ground at all. In fact, he tried to place his soles normally, but found himself unable to stand like that. It took a little getting used to, but ten minutes later he finally manged to stay relatively upright by shifting his balance ever so slightly with wigs of the tail, but now he was too tired to move after so much effort just to get up.
