Doraemon's Song (ドラえもんの歌 Doraemon no uta) is an episode of the Doraemon 2005 anime. This is the first anime adaptation of the manga chapter.
Gian happily invites a reluctant Nobita and some of his classmates to his concert. Not wanting to hear Gian’s singing, Nobita asks for a gadget from Doraemon. However, since Doraemon is unable to take out a suitable gadget at the moment, he gets Nobita to go to Gian’s concert first. Doraemon shows up later with the Noise-Cancelling Microphone to mute Gian’s singing.
As Nobita and Doraemon return home, the latter suddenly develops hiccups from swallowing something earlier that makes him want to sing. He sings to Nobita, who remarks that Doraemon’s singing is more horrible than Gian’s. Not understanding Nobita’s feelings, Doraemon runs to Gian’s house and almost wrecks his room with his singing. As Doraemon begins to malfunction without knowing it, he presents his horrible singing to Suneo and Shizuka who pass by, and begins to practice for his concert for that night. As the situation gets worse, Nobita goes to the future to seek help from Sewashi.
That night, Doraemon forces all the residents in the neighborhood to attend his concert and begins to sing, to the horrors of everyone. Nobita and Sewashi turn up at the venue in time to shut Doraemon down and bring him back home to fix him. They find a grasshopper in his body; which caused Doraemon to malfunction. Doraemon, Nobita and Sewashi send the grasshopper back to the grass and admire its chirping.
