Studio 4: Micro Set

The Micro Set is a room in Luigi's Mansion 3. It is found on the eighth floor of The Last Resort, Paranormal Productions. The set is made up of several oversized objects like nails, tools, and a cardboard box. Luigi can use the Poltergust G-00 on the large bills to turn them into regular bills and use the Suction Shot on the coins to turn them into regular coins and gold bars. When the film camera is used, the blue screen becomes the interior of a shed and reveals that the set is on a table.

The green gem can be found inside a bottle next to the cardboard box which Gooigi can enter.

Inside the box are multiple Gold Spiders and Morty's megaphone attached to a web. When Gooigi appears on camera, he must use the suction shot to open the box, where the giant spider will come out. Gooigi must use the torch to burn the giant spider and the web where the megaphone is trapped. Luigi can now grab the megaphone and return to Morty.

Trivia
