When Nobita feels like diving in his hometown, 多啦A梦 uses Underwater 泵 Simulator (架空水面シミュレーター・ポンプ?) to 泵 all the water to fill up water. That night, 多啦A梦 and Nobita use a Diving Mask Simulator to dive underwater. Later on, lots of fish, and a 鲨鱼 attack 多啦A梦 and his friends. So, 多啦A梦 puts a stop on the Underwater 泵 Simulator, but there is a girl named Sophia, lay down on the bushes in his town.
