The companion doll

"Oh. It's so cute." Chi Lian gushed. "You said it can walk on its own, right?" she asked T4.

"Yes host, the pingu companion doll is the most preferred companion for children and adults who live alone. It can be used as a conversational aid for toddlers who are struggling to talk. All you have to do is upload what topics you want it to discuss and it will do the rest." T4 explained.

Chi Lian studied the penguin; she remembered that back on earth in the old days there was a cartoon on television with a Penguin called pingu. Was it a coincidence that this doll was also called Pingu? Could there be a traverser on T4's world?
