Master Honekawa's "Do it Yourself"

Nobita and his friends are watching Suneo's videos at his house, where his dad is showing off how he made a desk and chair for Suneo using a DIY method. Nobita watches many more of his dad's DIY videos, and although he finds it annoying, he is still envious when he sees Suneo's dad using a professional German-made chainsaw. Later, when Nobita returns home, he sees his dad cutting planks in the yard with a saw. His dad says he wants to make a bookshelf for Nobita over the weekend, which makes Nobita very happy. However, the saw gets stuck in the planks and breaks when he tries to pull it out! Doraemon then takes out a "Carpenter Drink," and after drinking it, his hands transform into various carpenter's tools. Following Doraemon's advice, Dad drinks the "Carpenter Drink", and his hand suddenly glows, transforming into saw that can easily cut wood! Not only that, his hand can also turn into hammer and chisel, so Dad enthusiastically builds a bookshelf and even renovates the kitchen. Suneo's dad accidentally crashes his excavator into Suneo's house, so Nobita and his friends have to help Suneo rebuild it. However, they end up completely transforming Suneo's house, much to Suneo's mother's surprise. The story ends with everyone singing "Ode to Joy."
