Agostinha is the Lobster Princess. She is a very vain girl who wears her crown with pride, dreaming of the day when she will become the Lobster Queen. However, the path for her is still long as she still needs to learn at school how to help her friends, who are frequently hunted by Drylanders.

Agostinha is 7 years old and has the sign of Sagittarius (♐).
