Sydney is a contestant in Animal Crossing: Chic Craze. She is listed as second among her fellow competitors, and is the first koala contestant in the series.
The secret that this koala holds is that she would much rather spend her time cooking than modelling. Not much more is known about her besides this.
In Episode 2, she sends a letter to the remaining contestants saying how she's been doing well since her elimination from the competition.
Sydney's birthday is June 21.
Though she is the first to leave, this elimination actually comes to her as a relief. She uses this experience to help her in her cooking.
