Plot Overview


Differences from the manga

  • This episode is two manga plots merged together into one full-length story:
    • In the story surrounding the treasure, Mendō’s grandfather gives a copy of the map directly as he requests him to find the treasure, leading everyone to the frozen lake, then shows up again still in his bed on a sled pulled by two dogs to give out more copies and plays dead twice, annoying his grandson. The group reach a spider web mark which turns out to be the result of ice breaking, then meet the penguins, and from there reach directly the Mendō statue.
    • In the other story, Mendō introduces Matsu-Chiyo to the class including Ryūnosuke simply to be praised for its uniqueness, and it ends with giant Matsu-Chiyo hugging Mendō.
  • The Amusement Park and the Labyrinth are original in the anime.
