D-2 Hit Rock Bottom Objectives

Goal The security image revealed strange events in the Crystal Quarry at the bottom of the mine. Get there as soon as possible, and figure out what the Boos are doing with the ghosts.
Description According to the Toad assistant, ghosts-Boos especially-have been very active in the mine. Perhaps the security-camera photo will tell us what they're up to.
  1. Reach the Bottom of the Mine
  2. Inspect the Crystal Quarry

Reach the Bottom of the Mine

Luigi

Examine the photo that the Blue Toad dropped and allow E. Gadd to teleport you back to the Secret Mine. You will then be dropped off at the Chalet.

Luigi

Take the elevator to the airway and cross the bridge then enter the door on the left. Now that you are at Crossroads, activate the portal device and enter it to get across the gap. Take the frozen key and take it through the portal. Melt it with the lantern then use it to open the locked door on the west side of the room.

Luigi
Once at the Skip Slope, slide down and get the key on the right side. Once at the end of the slope, shake the barrel to get a little fan, which you will need to spin to reveal a door on the right side.

Luigi

Go inside to find the Smuggler's Hideout. Burn some logs and take the burning wood to the giant piece of ice, which will blast the window open and cause two Greenies and a Sneaker to appear. Defeat them and blow on the window to close it. Melt the remaining ice then walk through the door to enter the Shaft.

At the Shaft, you will have to blow on the valve to bring it to the bottom floor.

Inspect the Crystal Quarry

Luigi
Examine the wall to enter the Coward's Chasm. Enter the door into the Deep Hall, then go to the door on the right to get to the Pit Mine.

Luigi
Turn the valve to reach a lower level then tug on the rope by the machine to turn on the device. Turn the valve to move the mill and let the rocks enter the portal device.

Luigi
Return to the Deep Hall, then take a rock and burn it at the fireplace. Toss the rock at the frozen chain on the west side of the room, then pull on both chains to unlock the door. Enter to get to the Cinder Mine.

Luigi
At the Cinder Mine, turn the valve to start a small fire then take the log from the back of the room and use it to melt the ice on the west side. At the new unblocked area, shake one of the bags to reveal coal that can be used to shoot down the frozen key at the middle of the room. With the key return to the Deep Hall where you must defeat two Greenies. Enter the locked door to see a group of Boos trapping ghosts in crystals, which cause them to get stronger.

Luigi
Now that you're in the Crystal Quarry, look into one of the crystals to cause the ghost to escape. Beat the Strong Greenie, the Strong Slammer, and the Strong Sneaker. E. Gadd will then teleport you back to the bunker.
