The Tap Juice Conversion Adapter

Nobita and Doraemon want to drink juice, but his mother only lets them drink water. The Tap Juice Conversion Adapter Doraemon ordered finally arrives, and he takes the gadget and connects it to the kitchen faucet, so that the two can drink orange juice. But this way, his mother can't cook, so the two have to connect the gadget to the faucet in the yard, and then lead the orange juice to the room through the subspace pipe, and invite Shizuka to come home to drink.

Nobita comes up with a new idea and opens the "Nobita Juice Company", connecting the juice to the homes of Gian, Suneo and others with pipes, and charges them (only Gian is in the account). However, there are many troubles in the process, such as insufficient water pressure, different types of juice that everyone wants to drink, and the damage of the pipes caused a juice fountain to appear in the park square.

Finally, the two explain the situation to everyone, and Nobita Juice Company has to stop operating. When they return home, their mother is very angry when she sees that they have spent tens of thousands of yen on water.
