Trevor Ngai is one of the pre-made NPC Arts and Crafts Hobby instructors who comes from Hobbies, the secret sub-neighborhood introduced with The Sims 2: FreeTime. The other two arts and crafts hobby instructors are Demi Louie and Cassidy Monif. He appears in every neighborhood once FreeTime has been installed. Trevor can be made playable by befriending and asking him to move in, or by marrying him.
He has medium-length brown hair in a ponytail, grey eyes, and medium skin. Trevor is a Family Sim with the Aquarius zodiac sign. As far as personality, he is quite playful and somewhat nice. But Trevor is somewhat sloppy, shy, and lazy. He is mostly interested in Environment, Culture, Money, Politics, and Sports. Trevor has the same facial structure as Joel Jeffress. He is one of the few hobby instructors from FreeTime whose outfit and hairstyle don't change when he is first spawned in-game. Trevor's pre-destined hobby is Sports.
