Petri (リカRika?) is a snootymouse villager introduced in the Animal Crossing: New Horizons 2.0 update. She was revealed in the October 15, 2021 Animal Crossing: New Horizons Direct. Petri's English name references a petri dish, a dish used by scientists to safely store bacteria and mold. Her Japanese name, "Rika", comes from 理科 (りかrika?), meaning "science" and is also a Japanese female given name. As with her appearance, Petri has the education hobby.
Petri is a white mouse with large, round glasses that obscure her eyes. She has a blonde fringe across her forehead, and her nose and tail are black. The inside of her left ear is blue, while the inside of her right ear is red. She wears a doctor's coat with a black necktie.
Without her default glasses, Petri has dark, half-opened eyes with gray eyeshadow and black eyeliner that makes a small wing.
Below is a brief description of the snooty personality. For more information, click here.
Petri has a snooty personality, which means she loves make-up and gossiping. As a snooty villager, Petri will first appear rude and arrogant towards the player, often talking about herself and her own experiences. She also speaks about the style and appearance of other villagers, usually other female villagers such as normal, peppy, and other snooty villagers. She will soon warm up to the player, confiding in them about their own feelings but still keeping subtly rude. Petri will not get along with lazy villagers due to them not caring about their appearance or the lazy villagers hating what she eats, and she won't get along with jockvillagers because they will question her on her physical appearance and they won't worry about fashion. However, she will get along with cranky villagers due to their similar rude personalities, and usually normal villagers as well.
Petri was added on the October 2021 update.
Petri's preferred theme is civic. Her profile says:
Petri is always doing some kind of research. When she's close to a breakthrough, she will stay in her laboratory for days at a time...so maybe bring her a snack.
