I am sad to say that these Yetis were not very responsible when it came to contraception and practicing safe sexual intercourse. One day the female Yeti discovered that she was expecting, but did not want to keep the baby as she had no maternal inclinations whatsoever, and felt that she was not ready for such a responsibility.
When the baby Yeti was born, the Yeti couple left it at the foot of a snow-covered mountain, so that a pack of wolves might come and raise it (like Romulus and Remus, or Princess Mononoke or something).
At around this same point in time, a group of young women went for a skiing holiday. One of the women found the abandoned baby Yeti and immediately felt such a bond with it that she could not bear to leave it out in the harsh elements. She legally adopted the baby, and raised it as her own.
As the baby Yeti grew, she took him on many nature outings such as bug-catching expeditions. However, the Yeti developed a strong passion for fishing, so the young woman took him fishing every weekend. The Yeti became so adept at fishing (in freshwater, saltwater, rivers, the deep sea, you name it...) that the woman decided to open up a fish market so that they could sell the fish they had caught.
The fish market became an instant success for it was located within a geographic niche free from competing businesses, met the needs of consumers effectively through the utilization of the leading consumer behaviour and market research theories, and raised a high profile through social media marketing and public relations.
The young woman and the Yeti fished for the rest of their lives, and made a decent living from the profits of their enterprise.
