Summary: The episode begins with a flashback to Robby borrowing money from loan shark Yang.

Aboard the Nagaya Voyager, Robi describes the route from NEO Tokyo to Isekander. After Ikku announces three unknown ships are following them, Hatchi insists on stopping at the water-covered planet of Odwarla.

Hatchi drags Robby and Ikku to a seafood restaurant but when it comes time to pay, confesses he is out of money. Robby suddenly collapses and is taken to the hospital, where he is reunited with a beautiful nurse he dated on Earth. She tells him about a cash reward for catching the elusive Odwarla oarfish.

A flashback shows how Allo and Gras went from living in cardboard boxes on the street to working for Yang.

Ikku and Hatchi return to the restaurant to work off their debt. They decide to help co-worker Gyo-Gyo catch an oarfish as a wedding present. Robby shows up at the restaurant with an expensive set of fishing gear sold to him by the nurse. After hours of no luck, Next, Robby and Hatchi board Hizakuriger to search underwater. Unfortunately, the sinking robot quickly starts filling up with water. Robby and Hatchi manage to escape and Gyo-Gyo carries them to the surface. After retrieving Hizakuriger from the ocean, they capture an oarfish that had gotten trapped inside the hollow robot.

Back aboard the Nagaya Voyager, Robby, Hatchi, and Ikku calculate that after expenses they are still broke, and all they have left from their visit is a souvenir mug from Gyo-Gyo’s wedding.

GingadouThe route from Earth to Haccone stretches across 2,290,000 light years and 53 planets on the Galaxy Highway. This itinerary is a parody of the Tōkaidō Road and its 53 official post-stations. With NEO Tokyo (Nihonbashi) as station #1, the other planets follow the same numbering system:
#2 Nimoi (Shinagawa)
#3 Leontes (Kawasaki)
#4 Rose Goddess (Kanagawa)
#5 Grand Donut (Hodogaya)
#6 Tottska (Totsuka)
#7 Wisteria (Fujisawa, fuji means “wisteria”)
#8 Wide Mound (Hiratsuka, hiratsuka means “wide mound”)
#9 Oiso (Ōiso)
#10 Odawarla (Odawara)
#11 Haccone (Hakone)

odwarlaThe Odwarla post-station is built on an artificial, floating island shaped like a loaf of processed fish paste called kamaboko.
