My Pool is the Pacific Ocean

During the summer vacation, Nobita, Shizuka, Suneo, and Gian go to the swimming pool to escape the summer heat, but when they get to the swimming pool, they have to go home (although they play for a while) because of the crowd. After Nobita comes home, he asks Doraemon if there is a spacious swimming pool for him and Shizuka to play.

Doraemon takes out the "Expansion Pillsr", on the surface, it makes Nobita's bath bigger, but in fact it keeps the user in place. In fact, it is the effect after Nobita takes the medicine. Doraemon suggests that Nobita, Shizuka, Suneo and Gian go to Nobita's bathroom to play.

On the way, the two see Gian and Suneo playing football in the vacant lot. Doraemon takes the opportunity to enlarge the vacant lot so that Gian and Suneo can play football in the enlarged vacant lot (same as Nobita's situation above).

Then Shizuka, Gian, Suneo, and then go to the bathroom of Nobita's house to play . Nobita takes an extra space expander, which causes the space around him to becomes larger. At this time, Nobita's mother urges everyone to eat watermelon in the living room, but Nobita after walking on the water for a long time, he is tired and falls asleep.
