Polari

Polari is a elderly dark brown Luma who appears in Super Mario Galaxy. Polari is the one of the oldest Lumas and is Rosalina's most trusted adviser. He knows all about the observatory, and guides to Mario showing him a map of the space. Polari is Toadsworth's galactic counterpart, just as Princess Rosalina is Princess Peach's counterpart. Like Toadsworth, he is very protective of Princess Rosalina and is eldest of his kind. Polari might be the first luma Rosalina met, because of its age and because he's usally hanging around with her.
