Shizuka-chan ga Kappa ni!?

Synopsis

After Doraemon borrows 100 yen and mysteriously throws it into a grass field, Nobita questions his actions. Doraemon explains he's testing the Treasure Finder—a device automatically locating hidden valuables. However, the machine ignores coins under 1,000 yen, rejecting Nobita's 100-yen piece. Despite Nobita's frustration, they venture to Chinkara Pass, a legendary location rumored to contain 20 million ryō in buried treasure. The Treasure Finder remains maddeningly unresponsive, forcing them to search manually through challenging terrain and mysterious obstacles, questioning whether the legendary treasure truly exists.
