World 1

World 1 is the first world in super mario galaxy 2. It is the easiest world in the game and is good place for new players to get used to the game controlls and power ups. World 1 has a better range of exploration than all the other galaxies because it lacks missions that involve lava and moving platforms. The missions and bosses in world 1 should not prove much of a problem to Super Mario Galaxy Veterans. There are 18 power stars and green stars in this world
