During the summer vacation, Suneo, who is in a villa on the Yojo Peninsula, sends a letter to Nobita. Suneo seems to be enjoying his days at the villa with Gian and Shizuka, and there are pictures and letters that seem to be fun inside. Nobita saw it and cried, saying, "I want to take a walk on the seabed without going into the sea!"
Doraemon, who felt sorry for Nobita, suggested that he go to the Yojohan Peninsula with "Anywhere Door". However, Nobita, who cannot swim, says, "I want to take a walk on the seabed without entering the sea!" When Doraemon heard that, he took out the "water repellent rope". If you cut this rope, tie it in a loop, and enter it, it will not let the water out, so even people who can not swim can enjoy a walk on the seabed.
Nobita and his friends arrived at Yojohan Island at the door everywhere and decided to take a walk on the seabed using a water-repellent rope. Nobita was very happy with the beautiful scenery under the sea ...! ??
