Libra

Libra is Olimar's daughter. It is also a ship part in Pikmin. Her usual captain color is yellow.

How to unlock it
She is in fact a playable character. She is a little difficult to unlock. First you must defeat the Flaming Supershear and bring the Wonderful Gold back to the pod. Then when you return to Suma dock, Libra will appear next to the first tourist pod. When you talk to her she will say" Dad im sorry I snuck out, I was jealous of Sagittarius." She then says if you give her a beautiful necklace then she will help explore the world. To get the Beautiful Necklace you must talk to Sigan about it. He then says that he will turn the Wonderful Golf into a necklace if you kill the Super Watershear and give him the Yummy Goop. Once you give the Wonderful Necklace to Libra then she will gladly join you as a playable character.
