His older brother. Very smart but also a buzz kill to Navi. Navi just wants to run around and hop into whatever place or situation he wants to be in. He knows how the world works, and he can protect himself. He doesn't need a big brother constantly telling him what to do! >:(

His little brother. Estrella swears he doesn't know what to with Navi at times. While he is talented and has very interesting findings, he's gonna get himself into some bug trouble one of these days.

His big sister. They both had the biggest sibling rivalry ever! Navi loves to get on her nerves.

Her annoying little brother! Plays around too darn much! Nebby always has a way to get back at him though.
