The water heater is on the main level of the house, which includes all of the major plumbing: 3 bathrooms, kitchen and laundry area; the other two levels (1/2 flight up and 1/2 flight down from main level) do not have plumbing. By the way, the house is approx. 2471 sq. ft.
Fire Blast is the main choice in the second moveslot as it allows Nidoqueen to hit Steel-types who don't care about Earthquake, such as Skarmory and Forretress, for solid damage. However, Super Fang is a viable alternative, allowing Nidoqueen to immediately strip any switch-ins of half their health, bar Ghost-types. Stealth Rock is the main option in the fourth moveslot, as it allows Nidoqueen to further support her team; she can set it up in the same situations where she sets up Toxic Spikes.
Also called Nitsume, Unagi or Kabayaki. It is a sweet and salty sauce that goes great over grilled fish or chicken and is a common drizzle over sushi. Traditionally it is used on Japanese grilled eel and eel rolls. I also use this sauce over fresh cooked noodles for a quick snack. 1/2 cup of dashi may be added to create a richer, more authentic flavor. (Dashi is a fish stock that must be made at home).
