Below is a brief description of the uchi personality. For more information, click here.
Rocket has an uchi (or "Big Sister") personality, a combination of the snooty, normal, and peppy personalities. Once she becomes a close friend of the player, she will act like a big sister. She may have disputes with snooty and cranky villagers since they enjoy spreading rumors.
Rocket's house has a mix of pink furniture and exercise equipment. Her wallpaper is the skyscraper wall, and her flooring is the charcoal tile. She has the Lovely bed and dresser, a No. 4 shirt, and a pink-zap helmet. She also has a treadmill, a butterfly machine, and a lat pulldown machine. Rocket plays "K.K. Adventure" on her hi-fi stereo.
Her Japanese name and the shirt she wears represent that she is the fourth superhero introduced in the Animal Crossing series, after Kid Cat, Agent S, and Big Top, in that order, who first appeared in Doubutsu no Mori e+.
