Cutie

Cutie's description on the official Planet Dob website states: "I'm a popular person in the city. I run a shop with my best friend, Squirrel "Mill". My best friend Mill seems to be lost in Peace 3. Let's find them!"

It is possible the name on their shirt and on the site listing may be a translation error, as their name in Japanese is "キューティ" which translates to "Cutie".
