Jaiko is reading a book, and becomes ill as Gian gives his sister more sweet potatoes, and gets shocked. Meanwhile, Doraemon takes Nobita on a trip through a gadget that shrinks them and lifts him to a tree, where a Leafbelt enables him to attach to and fall safely on a falling leaf. He finds he likes it and introduces it to Shizuka and Suneo. But when the last leaf on the tree outside the window falls, Jaiko thinks she'll die.
- In the original version Jaiko is eating sweet potatoes while she's reading her book, but in the U.S. English version, she's eating popcorn.
- Jaiko's belief that she will die once the last leaf falls is instead changed to her believing that the goblins will kidnap and take her into the forest.
