Nick Knack is a pre-made adult Sim who resides in Twinbrook, the world introduced in The Sims 3: Ambitions. He lives with his wife Pattina and their daughter Julienne, who is a young adult, in a wealthy residence at 26 Puddlewick Drive. Nick is said to be the "glue of the family." He has the Can't Stand Art trait, which conflicts with Pattina's Artistic trait. They however share the Perfectionist trait. His name is a pun of knick-knack. When Twinbrook is first played, he is 5 days away from being an elder.
