Sandy Grand Hall

The Sandy Grand Hall is a location in Luigi's Mansion 3. It is found in the Tomb Suites on the tenth floor of The Last Resort. It is north of the Elevator Hall, and south of the Altar Chamber.

The purple gem is hidden beneath a pyramid-shaped sand dune on the left side of the pyramid. The yellow gem is found on the southeast corner of the area with two missing segment, restoring the parts of the large stone snake with the Dark-Light Device causes the gem to come out of the snake's mouth. If Luigi enter the cutout island, he'll be attack by a horde of Mini Goobs and a Hammer, which also reveals a treasure chest. There is a magic lamp which reveals a bunch of coins, bills, gold bars, and a Golden Goob Luigi must examine the left statue to open the door to the Altar Chamber. Once Luigi escapes from the bottom the pyramid, he encounters Serpci again and the battle begins.

If Luigi returns to the Sandy Grand Hall later on, he may see a bunch of Goobs with brooms.
