C-2 Underground Expedition Objectives

C-2 Underground Expedition Walkthrough

1. Find Your Way Underground.
2. Look for the Missing Clock Hands.

Find Your Way Underground

From Clockworks Court, head east towards the X on the map. A door will open on the floor, which lets you into the Storm Cellar. When you get to the Storm Cellar, you will be met by two Greenies, which you will have to defeat, including one more hiding under the bed. Drop the rock that one of the Greenies used onto the lever to open a path to the door leading to Canyon Hall.

When you enter Canyon Hall, walk east and remove a sheet off the wall on the right to reveal a hole which leads to Canyon Narrows. Grab ahold of the lift and go to the other side of the canyon where you will find a hidden bonus area. Return to Canyon Hall the same way and defeat the Sneaker that appears.

Enter the door to the north to get to Roundhouse Pit and tug the rope three times to tear it down. Enter the door to Pit Slide where Luigi will slip and fall down the sand slide. Collect the gold bars and coins as you fall. At the bottom of the slide, enter the door that leads to the Quarry. Once inside, walk down the steps to the lower level and walk towards the mine cart towards the right. Tug on the rope until it lands in the hole. As sand fills up the room, defeat the five Greenies and three Sneakers before exiting through the door on the right.

Look for the Missing Clock Hands

In the dark Antechamber, you'll find a ball of spider web which you will light with one of the torches at the entrance. Use the flaming web ball to get through the giant webs that block the path. When you get to the end, you will arrive at the Tomb. Open the coffin in the center to find one of the clock hands, which an Ancient Poltergeist will steal.

Defeat the mummies that appear by flashing a light at them to cause them to run forward. Get them to run into a wall, which will cause them to fall and allow you to suck off the mummies' bandages and reveal a Greenie. Once all three are defeated, E. Gadd will bring you back to the bunker.
