Super Mario Galaxy Tips

Finding Luigi (Pt. 2)
The last location that Lugi is in is at the Second Galaxy you can access, first level. Activate the Bee Mushroom and go behind the waterfall. Fly up to the other part of the level (where the Wiggler is in later missions) and you will see Luigi clinging for dear life on a tree. Kill the orange bug, then spin attack Luigi off the tree to get a normal power star.
