Eu encontrei! Na verdade, alguém em outro site encontrou. Mas aqui está: uma história chamada " A Era do Plástico " em uma antologia chamada À deriva no espaço e outras histórias publicado em 1974. Um Excertos mencionados em Goodreads sugere sua habilidade de moldar seu rosto:
When he awoke, Paul was unaware of the change that had come over him. He was a little groggier than usual, but otherwise, he felt fine. It was only as he began to dress that Paul noticed the change. His skin. Somehow, it was different. It felt smooth and pliable— like the plastic toys that lay scattered about the room.
Obrigado a todos que ajudaram ao longo do caminho!
