Nobita + Pigeon =? / Strong Stone

Nobita is determined to run for exercise in the new semester, but he is lazy and unwilling to stick to it. Seeing that Nobita is not strong-willed, Doraemon criticizes Nobita and takes out the "Strong Stone". Seeing that Nobita thought he is joking, he shows it to Nobita's father. Sure enough, Nobita's father cannot drink in the set 10 minutes, and he will be attacked every time he wanted to drink. After 10 minutes, Nobita's father is finally able to drink, but he collapses due to exhaustion. He wais still lying on the ground when Nobita is chased out of the door by the "Strong Stone". Nobita decides to use the "Strong Stone" to urge himself to run and set the time to one hour. Just as he is preparing to start, it starts raining. Nobita wants to postpone it until tomorrow, but is attacked by the "Strong Stone". Nobita has no choice but to run in the heavy rain. Doraemon tries to control the "Strong Stone", but fails, so Nobita has to run for an hour. Nobita finally runs for an hour with dizziness and weak legs and comes to the archway at the entrance of a shrine (there is a narration-style caption above the screen). At this time, the weather clears up, and Doraemon excitedly runs to greet Nobita, telling Nobita that there is nothing he can't do as long as he persists. Unexpectedly, the stone still chases Nobita. It turns out that Nobita makes a mistake in the time unit and set the running time to one year. Nobita really can't persist, so he can only find ways to avoid the stone. Nobita first falls into a deep pit of construction, thinking he has escaped, but finds that the stone chases him back. Then Nobita asks Gian for help, but Gian still fails after fighting with the stone with a baseball bat. Seeing this, Doraemon takes out the "Anywhere Door" for Nobita to escape, but Nobita runs into Shizuka's bathroom out of habit. Doraemon finds that Nobita runs into Shizuka's bathroom and deliberately blocks the "Anywhere Door" with his body to prevent Nobita from leaving. Shizuka doesn't react to what happened the whole time. At this time, Nobita has an idea and borrows Shizuka's clothes to wear. At first, the stone doesn't recognize Nobita in woman's clothing, but Suneo passes by and calls Nobita's name, causing Nobita to be recognized. However, after Nobita takes off his headscarf, he is still chased. Fortunately, Doraemon wraps the stone with the "Time Cloth" in time, and it stays in the cloth for a year before it stops. Finally, Doraemon warns Nobita that he has to cultivate his strong will by himself, but Nobita says helplessly that too strong a will will destroy himself.
