William Enriquez is one of the pre-made NPC mail carriers who resides in Riverblossom Hills, the neighborhood shipped with The Sims 2: Seasons. The other two mail carriers are Kerie Bradshaw and Blake Fuchs. He can be made playable by befriending and asking him to move in, or by marrying him. William has the same facial structure as Quinten McAuley. He has brown hair, brown eyes, and dark skin.
William's Aspiration is Popularity, and his zodiac sign is Leo. As far as personality, William is very outgoing, playful, and a little bit active. But he is very sloppy, and somewhat grouchy. When it comes to his skill points, William is halfway towards maximizing the mechanical and cleaning skills, and is over halfway towards maximizing the body and creativity skills.
He is mostly interested in Entertainment and Work. William has facial hair, which is rather uncommon for a standard NPC. Even though he has brown hair, his SimDNA in SimPE confirms that his natural hair color is blond. Unusually for a pre-made NPC, William has the memory of meeting Kerie Bradshaw, as well as having a pre-set relationship with her.
