Zu is a lively, curious and intelligent girl. There’s just one small detail that sets her apart from other girls: she is the owner of the São Paulo Zoo. Zu’s Zoo is a fantastic, fun place, filled with music, eccentric employees, and problems to be solved. However, Zu is not alone in her quests: there are the animal caretakers Mrs. Mimi, Mr. Passarinho and Mr. Gelado; her faithful companion, Nuno, and her big brother Eric. They are the ones who are always with Zuo on her quests.
