Main Tank - Top

The Main Tank - Top is a location in Luigi's Mansion 3. It is found in the Boilerworks on the second basement floor of The Last Resort, located above the Main Tank. Clem is fought here.

The hole is surrounded by spikes which will damage 20HP to Luigi, so he must avoid the spikes and launch Clem to deflate his inner tube for him to be vulnerable. Gooigi cannot float on the inner tube, but he can assist whenever Clem is forced out of the water by capturing him. After Clem is defeated, Luigi or Gooigi accidentally drops the elevator button down to the Main Tank, requiring Luigi to drain the water.
