Doraemon Specials (1970) : 3x14

For Doraemon’s birthday, Nobita surprises him with a ticket to the 22nd-century Funny Castle, a magical sweets studio where the prize Dream Dorayaki Cake is made by mechas using recipes on the spinning Ocasic Record created by pastry genius McCarron. Inside, an upset usher named Candy reacts badly when he learns Doraemon is a cat-shaped robot, and Nobita uses an Inanimate Baton to miraculously restore a toppled macaron tower. Inspired, Candy rushes off clutching a record—but soon Gian, Suneo and even Shizuka vanish and eerie duplicates appear. Strange glitches erupt throughout the castle, and Nobita must unravel the mystery to save his friends in a sweet-but-perilous adventure.
