Locker Room

The Locker Room is a location in Luigi's Mansion 3. It is found in the Fitness Center on the thirteenth floor of The Last Resort. It is west of the Gym Lobby, east of the Weight Room, and south of the Shower Room. The white gem can be found here.

When Luigi enters the Locker Room, an Oozer can be seen with a spraying can, then hides in one of the lockers, which contain Mini Goobs and Mini Hammers, all of which must be defeated to proceed. Luigi cannot enter the Shower Room since there are towels blocking the door, therefore, he must enter the Weight Room to continue. On the left side of the Locker Room, there is a vent where Gooigi can enter, underneath which is a bunch of mice and some gold ones. Luigi must suck near the hole where the mice will come out after Gooigi tries to suck from underneath, in order to complete the achievement.
