Disney has yet to make a Princess of Genovia doll, certainly one is overdue. Unlike the other animated princess stories, the fictional Princess of Genovia does not use magic, witches, or fairy god-mothers to solver her problems. This princess deals with reality like a normal human would.
The national seal for Genovia slightly differs for the royal arms. The primary difference is the missing letter 'G'. It can be found on the royal badge, but as for the national flag the arms are missing the special 'G'.
