List of Boos in Luigi's Mansion 3

This article is under construction. Therefore, please excuse its informal appearance while it is being worked on. We hope to have it completed as soon as possible. This article is currently under construction by The Mansion.

During the events of Luigi's Mansion 3, there are a number of Boos to be found throughout The Last Resort. With the exception of the Master Suite, there is one Boo located on each floor of the hotel. They appear after obtaining the floor's elevator button, and leaving and returning.

Unlike previous entries, which saw the HP of Boos rise with each area, the HP of all Boos remains fixed at 20 HP. Additionally, the precise location of Boos is randomized.

This is a list of all Boos that appear in the game (excluding King Boo), in the order of ascending floor number. There are 17 Boos total (16 excluding King Boo), each of which are unique. Collecting all Boos will grant the player the "Captured All Boos" achievement, unlocking the Flashlight Type-B for the Poltergust G-00.

The following chart shows each Boo's name, the floor it is found on, the specific rooms it can hide in, the origin behind its name, and its names in Japanese, Chinese and French languages.

Trivia

• Some of the Boos return from previous entries: GumBoo, Booigi, Boogie and Kung Boo are from Luigi's Mansion, while Boolldog is from the 3DS remake and Luigi's Mansion: Dark Moon.
• When Gooigi begins vibrating in response to the presence of a Boo, the controller vibrates in Morse code reading "-... --- ---", translating to "Boo".
• GumBoo's second quote is a reference to the late Justin Wilson, a Southern American comedian and chef who was known for his catchphrase, "I gar-on-tee!" (I guarantee).
