Using the Favor Box to Go to a Winter Camping

On a cold day, because the heater at Gian's house broke down, Nobita and his friends have to run around in the empty lot with Gian. Just then, Suneo's cousin, Sunekichi, shows up and takes Gian and Suneo camping. Nobita, not invited, returns home, bored. Doraemon pulls out his "Favour Box" and conjures up a TV, but Nobita, bored, turns it into various objects. Nobita and Doraemon take the "Favour Box" camping and compete with Suneo to see who have the better equipment. At first, Suneo's friends have the upper hand thanks to their solar batteries, but after a while, the weather turns cloudy and the batteries run out. Doraemon and his friends transform the "Favour Box" into a mailbox, put their photos in it, and mail them to Shizuka. In order to defeat Nobita, Suneo's cousin takes out a robot and uses a rope to tie up Doraemon and Nobita, but accidentally ties them up as well. They are finally rescued by the postman who comes to collect the mail. Gian takes the "Favour Box" and uses it as a heater, but Nobita turns it into an air conditioner to give Gian a chill.
