The kids find some ambergris, a valuable but illegal bit of whale excrement, and try to find a buyer. Meanwhile, Bob and Linda meet Mr. Fischoder's oddball brother Felix, who offers to renovate their bathroom.
- Didn't Think This Through: Louise goes to make the deal with the Nose alone. The Nose clarifies this and because she's a little girl and all alone, he only gives her $12 instead of the full $30,000.
- Eye Twitch: As her sanity goes down, the frequency of Louise's usual eye twitch goes into overdrive.
- Gold Fever: Louise becomes increasingly unhinged as she becomes obsessed with the money she could make selling the ambergris.
- The Nose Knows: Mickey's aptly nicknamed criminal friend, The Nose.
- Only Sane Man:
- Bob throughout the subplot with Felix Fischoder, and he grows increasingly pissed off at what Linda and Felix are doing to the bathroom when he repeatedly asks and then begs to just call a freaking plumber.
- Tina in the main plot pulls a Bait-and-Switch on Louise for the ambergris after seeing what the obsession is doing to Louise. Tina finally has to destroy the ambergris when she gets cornered by a manic Louise, Mickey, and "The Nose."
- Sanity Slippage: Louise goes full blown nuts as greed over the ambergris drives her batty.
