Doraemon Specials (1970) : 3x8

Today, September 3, Nobita and his friends secretly renovate Doraemon’s cluttered closet as a surprise birthday present. With Dorami’s Inventing Machine, Daito Drink, and an “anything material” box they build new tools, a massage chair, and decorations while distracting Doraemon (Suneo’s photo shoot, Shizuka’s bath salts, and Gian’s singing). The reveal goes well until the new gadgets spiral out of control and briefly explode, but the mishap is forgiven. The group moves the celebration to Nobita’s yard, Doraemon is deeply thankful, and everyone joyfully sings “Happy Birthday.”
