2112年 ドラえもん誕生

Doraemon comes off the line at the Matsushiba Robot Factory in 2112 as a yellow cat-type robot, and a time disturbance during assembly costs him a screw. Robot school does not go much better, and after a mouse robot chews his ears off and the wrong pick-me-up leaves his plating peeled and his voice hoarse, he ends up blue, earless and rough-throated. Sewashi Nobi buys him anyway, which is how he reaches Nobita. This short film is the franchise's origin story rather than a regular adventure.
