Should the player ever lose sight of the ghost while it runs through the galaxy (as it does move considerably faster than Mario), they can use these arrows to track the ghost's previous movements. To activate the ghost, the player must have either Mario or Luigi touch it as it runs in place near the start of a galaxy, after which it will take off running through the galaxy, leaving a trail of green arrows on the ground behind it. Once created, a ghost can be found at the starting planet / area of each galaxy for which the player has followed the procedure to create it. The ghost that is created will always take the form of a translucent Luigi, and will never take the form of Mario. The ghost lying on the ground near the Comet Medal in the Throwback GalaxyĪfter the player has completed a mission with Luigi, and upon returning to Starship Mario, the player will receive a message saying that a ghost has appeared in the galaxy from which they just came.

Therefore, the player has more control over where and when ghosts are created later in the game, as opposed to earlier in the game. Before this point in the game, ghosts can only be created if the player agrees to let Luigi take over a particular mission when he appears at the start of some galaxies. For this reason, it is considerably easier for the player to create ghosts after Mario has defeated Bowser in Bowser's Galaxy Generator at the end of the game, as Luigi now appears onboard Starship Mario, and is available for the player to use at any point. A ghost can be created at any point in the game, but will only be created when the player successfully completes any mission in a galaxy while playing as Luigi instead of Mario or by having 9999 Coins in the Coin collection in Starship Mario, in which would cause a ghost to appear in all galaxies, all missions leaving no need to play as Luigi. Mario encounters a ghost at the start of the Throwback GalaxyĪ ghost is a helpful character that appears in the Wii game Super Mario Galaxy 2.
