Ultra Ring

Nobita's father makes his mother angry because he doesn't do housework. Nobita always loses the finger wrestling game with Gian, Shizuka and others, and is pinched very painfully. In order to help Nobita, Doraemon gives Nobita the "Ultra Ring". Nobita uses Doraemon's face to experiment, and it really works. Nobita's mother loses the ruby ​​ring given by his father. Nobita remembers that he loses the ring when he is playing with Shizuka, so he has to give the "Ultra Ring" to his mother. Mom puts on the "Ultra Ring" and sees Doraemon is bounced away because he has dust on his nose because he helps her clean up. Nobita first goes to the empty lot to look for Shizuka, but he doesn't find her and is hit by Doraemon. Then Doraemon goes to stop his mother, and Nobita goes to Shizuka's house to look for the ring. When the mother accidentally pushes Suneo's mother, who is showing off her beauty treatment, away on the street, tears the sleeve of her kimono, and chases her, she knocks Doraemon to Shizuka's house. As a result, Nobita and Shizuka are crushed to the ground by Doraemon who is thrown away by the mother. Nobita's father goes to buy a cake to cheer his mother up, and happens to see Nobita's mother pushing down a bicycle that almost hits him, breaking a billboard that almost crushes him, and knocking down a telephone pole, which scares him. When Doraemon, Nobita and his mother return home (the mother should have taken off the ring at this time), they see that his father has cleaned up the house and asks to make dinner, which is very strange.
