Carey stared at herself in horror, realizing something was happening to her body. The strange land seemed to affect her subtly as the brightening of the moon intensified the feeling. It was changing her. It was changing her very form. Her human features began to be overwritten by a pink ooze, seemingly appearing from her own pores. Her body was conforming itself to the land, making her fit. She wanted to turn back and run for the door than led her here, she wanted to escape. But the land whispered into her ears.
"Stay with us... Be our friend..."
The disembodied voice struck fear and calm into her soul. She shook herself and replied shakily.
"N- nooo!"
The voice asserted itself again, but stronger this time
"Stay with us...Be our friend... Friendship is magic..."
Carey could no longer move, locked in by an unnatural sense of fear and happiness. She felt fully alive and happy oustide, but inside she felt nothing but pain and fear and helplessness. Her last words were cut short as her mouth twisted into a horsey feature of her own transformed imprisoning body.
"Noooo Noo-m aafah;j - Hi I'm a pony!"

And thus ends the former human nature of this particular person to be integrated into pony fandom forever!
