156
Frustrated by the irritating behaviors of those around him, Nobita asks Doraemon for a new device. Doraemon provides a tool named Magnify Bad Habits Gas, which has the ability to alter negative habits into bizarre manifestations. For instance, when Nobita uses the gadget on his own habit of picking his nose, the resulting booger transforms into a large, pink, soft, and bouncy ball. This example illustrates how the device converts common annoyances into unusual and often humorous physical changes, addressing Nobita's desire to eliminate the bad habits that bother him and others.
