This is a walkthrough for how to get the red megaphone in Luigi’s Mansion 3.
Speak to the director and he’ll tell you he wants to get his red megaphone back because he’s not a director without it. First of all, you want to go into each room and flash each TV with the bulb on the Poltergust G-00. By going into each room and turning on the TVs this allows you to warp between each room nice and easy. By going to each room this allows you to asses the layout of each set and orientate yourself. Do the left rooms first and then do the right rooms.
Get the bucket
The first task is to get the bucket. This is next to the director on the right-hand side. Pick it up with the Poltergust G-00 and then warp through the TV to take you to the horror set. Place the bucket in the well get Gooigi to stand in front of the camera and then start filming.
Get the water
As Googi interacts with the bucket in the well to get it and pick up the bucket with the water in it. Once you have the bucket teleport out of the room and then teleport to the set with the castle. Get Googi to stand in front of the camera and then start filming again. Have Gooigi use the water on the vines and they will grow. Climb to the top of the plant and grab the torch.
Light the torch
Teleport back out of the room and this time go to the set with the buildings. Have Googi stand in front of the camera and start filming with Luigi. Now the buildings will be on fire you want to use Googi to light the torch and then teleport back to the main area.
Light the web on fire
Finally, teleport to the final room where the spider’s web is and start filming with Googi in front of the camera. Use the suction shot on the cardboard box and open it up. Use the Poltergust G-00 on the torch and carry it over to the web and burn it.
Congratulations! You now have the red megaphone, which you can give back to the director.
