Luma Island

Luma Island is the home base in Super Luigi Galaxy. It starts off as a large island with a few Lumas and Yoshis and Willy. As you progress, the island extends. New characters take up residence on your island as you meet them.

The Chimp - Back for more fun and challenges!

Nate The Friendly Goomba - Met at Goomba Jungle Galaxy. Friendly, good Goomba who loves to read.

Sonic The Hedgehog - Met at Speedy Spin Galaxy. Luigi's best friend.

Your island also grows as you you progress. Smaller islands connect to Luma Island as you see more and meet new things. At the very end of the game, you even acquire The Eggy Heads, a band of Yoshis and Lumas that plays songs! Also, if you connect to someone over the internet, they can send you 1-Ups and Hungry Lumas.
