Neptunia's base is a building located at the bottom of the ocean just past the river mouth leading from St. Canard. It is a rather dualistic construction, being luxurious on one hand and a garbage dump on another. As well, despite being on the ocean floor and home to Neptunia, a creature who's principally a fish, air supply is present to accommodate visitors, whether they are the willing or the unwilling sort.
Neptunia had her house built after her mutation. It appears to be composed of rocks and shells and is comfortably roomy inside. Many chambers are filled with air and alternate walkways with waterways. This way, both land-dwellers and (small) ocean-dwellers can enter and leave while the humidity is comfortable for Neptunia to function in. Other than her living space, the base also is a collection spot for waste from the surface. Neptunia stashes it away in cells to make a point when she has prisoners.
Darkwing Duck and Launchpad McQuack ignore several warnings from Neptunia to keep a distance, so she has Billy capture them and bring them to her base. She locks them up in one of the garbage cells, calling four electric eels to function as bars. After twice dumping junk on their heads, she gives her background story as to why she's been attacking St. Canard. Launchpad is moved, but Darkwing reacts with derision. Angered, Neptunia leaves to initiate her master plan to flood St. Canard. When she's gone, Darkwing uses a metal pipe among the debris to short-circuti the eels and escape.
