Stuff Only for You Gas

Nobita excitedly shows Shizuka his comic, and Shizuka says she wants to go to an art exhibition with Dekisugi. Gian snatches the book away, making Nobita very angry. When Nobita gets home, he finds the dorayaki is moving. It turns out Doraemon has sprayed "Mine All Mine Spray" on the dorayaki. Doraemon experiments with his piggy bank, and the spray works. Nobita takes the gadget and gives it to Shizuka, spraying the gas on comic. Unexpectedly, Nobita accidentally sprays the gas on the teacher, making him the teacher's private property. As a result, Shizuka can't wait for Nobita. (Nobita originally intends to spray the monkey in the tree.)
