Sabastian Collins is one of the pre-made NPC Nature Hobby instructors who comes from Hobbies, the secret sub-neighborhood introduced with The Sims 2: FreeTime. The other two nature hobby instructors are Naenae Philippine and Adriana Shaikh. He appears in every neighborhood once FreeTime has been installed. Sabastian can be made playable by befriending and asking him to move in, or by marrying him. He wears a PlantSim outfit, and has short curly black hair with a headdress resembling those worn by the locals of Twikkii Island, light blue eyes, and medium skin.
Sabastian is a Romance Sim with the Libra zodiac sign. As far as personality, he is very outgoing, quite nice, and somewhat playful. But Sabastian is very sloppy and lazy. He is mostly interested in Weather, Culture, and Entertainment. Sabastian has the same facial structure as Amar Larrea. He is one of the few hobby instructors from FreeTime whose outfit and hairstyle don't change when he is first spawned in-game. His pre-destined hobby is Arts and Crafts.
