Penny is a rather anti-social Toki when it comes to her own species and most other animals. Even humans will most of the time only get an angry growl in return for a friendly 'hello'. Though at times she does (somehow) take a liking to another creature and tries to befriend it shyly. However, she is very fond of her owners, which raised her, and is extremely loyal to them too. Unlike her sire, who is a rather awful 'singer', this girl has a truly beautiful voice and sure knows how to use it. She is often heard singing her handler to sleep and the entire tribe adores her daily lullaby. Her owners even encourage her to sing, be it for the soothing atmosphere in the village, earning a but of money as street performers when visiting the local city or simply to enjoy a festival with her voice mixed into the traditional music. Penny might be anti-social, but when she sings nothing really bothers her and she can even enjoy having people cheer her on and approach her to a certain point.
