How to Unlock Baby Luigi in Mario Kart Wii

Unlock Master Ghosts

Start playing the Time Trial. You will need to unlock 8 Master Ghosts. You can race against that phantom data while playing the Trial of Time. You can unlock Master Ghosts by defeating the Staff Ghost on each lap. Normal ghosts have "Nin★" written next to the name.

Select the single player mode (Single Player) from the main menu (Main Menu). Then choose the Time Trial game.

Choose any character. Since you need to race as fast as possible, choose the character and vehicle you feel most familiar with.

Select any lap. You will need to win at least 8 races so choose the ones you know best. That way you will feel less inhibited.

Specter data selection. After selecting the lap, you can select the Ghost data you want. Select the data that says "Nin★" next to the name.

Racing with Ghosts. The race will begin and you will see the Ghost appear on the track with you. You need to get to the finish line about 7 seconds faster than that Ghost to unlock Master Ghost. The number of seconds needed to be faster will vary from Ghost to Ghost, so try to get as far away from Ghost as possible.

You should see a text at the bottom of the screen that says 'A fast staff ghost has appeared!).

You don't need to defeat Master Ghost, just unlock it.

Repeat the steps above until you have unlocked 8 Master Ghosts. Beat the normal Ghost in 8 different races to unlock 8 Master Ghosts.

Once you've unlocked the Eighth Ghost, you need to return to the Character Selection panel for Baby Luigi to be unlocked! Exit the game, return to the main menu (Main Menu) and then go back to the character selection screen.

Choose the character you use in the Time Trial races. So it's done! You should see a line that says 'Congratulations! You have unlocked Baby Luigi (Congratulations! You have unlocked Baby Luigi!).

Race 3,150 Times

Race as much as possible. If you can't beat the normal Ghost, you can still unlock Baby Luigi by racing 3,150 times. All regular laps or battle laps count, except for the Time Trial lap.

Both online (online) and offline (offline) laps count.
