Random Disk

A music show is coming up at school. Shizuka, Dekisugi, Suneo, Gian, and Nobita are selected to perform and stay back to practice, but Nobita still could not master his instrument. Nobita returns home, and is forced to get the clothes off the line by Mum, but flees back to his room to seek Doraemon's help. Doraemon, who is busy preparing for a date with Mii-chan, gives Nobita a pair of Random Disks that allows Nobita to do the housework.

Later, while Doraemon goes out to date with Mii-chan, Nobita proceeds to Shizuka's place, but he drops the instrument and attracts the attention of a dog, who picks it up and runs away. Nobita uses one of the disks and chases after the dog at full speed. When he finally catches up with the dog near an airport, Nobita foils a robber's attempt to escape from the police by pushing him to the ground at sumo's strength, and the robber is arrested.

The policemen send Nobita and the dog to Shizuka's house, who uses the other disk to record Shizuka and Dekisugi's practice, but Gian pays a visit to Shizuka's house with a worn-out Suneo and begins to sing, causing an as-white-as-sheet Suneo to pull Nobita's ears and recording Gian's singing. The next day, during the music show, Nobita unintentionally screws it up when he sings to Gian's song. A pale Nobita apologizes.
