almost immediately, Mr Vonst felt a pain in his butt, and jumped outta his seat. he looked behind him and gaped. he saw that a bushy tail as long as his arm was sticking outta his back, just above his butt.
"Oh my." he said, surprised. "I seem to have grown a tail!"
There was a strange tingling from his ears, and he reached up to feel them grow much larger. They became pointed, then they quickly perked up. his attention returned again to his feet. He took off his slippers, and saw they were getting much longer. Fur overtook them and from the toes stretched his claws. Some joints clicked, and his ankles now resembled backwards knees. He felt his back shift, making him stuck on all fours.
he was impressed by the long muzzle that stretched out from him. The short gray fur around his nose and mouth was a pleasant compliment.
as he removed his clothes, the final changes went underway.
His hands popped; His fingers became stiff, shortening while his fingertips and palms swelled with padding.
His ribcage pushed out and his waist shrank. More popping noises could be heard as his body adjusted to quadrupedal motion. he leaned forward as his arms and legs shortened; with a final pop, his body slipped into the sitting position of a dog; his face pushing out slightly.
