After boasting about possessing a ranch, Nobita was prompted by Suneo's bragging to reveal whether or not he had one as well. Doraemon subsequently won several lotteries for worthless planets in the region between Mars and Jupiter. When Suneo and his companions arrived at the ranch, Nobita accidentally read the final lottery number to the go-anywhere door, leading them to a fantastical area. As Nobitas toy horse frolicked due to its wind-up life gadget, Suneo and his friends became fascinated with bringing their own toys to life in this area. Consequently, they decided to construct their very own clockwork city.
