In the film, Fuko is one of Mafuga's parts that were split by Noajin in order to seal the demonic beast. After Noajin sealed the most dangerous and evil part into red egg deep within the volcano of the forbidden island, the other two were also sealed along with Uranda's body in his tomb. However, both eggs were revived thanks to the Storm and the Arashi Tribe's attempt to revive Uranda. Both eggs each went on their way, very, very far away.
Later, after the storm calmed down, one of the egg is found (tripped) by Suneo when he attempts to play with his toy car, results in the shell breakage and a wind-like spirit emerges from it and also Suneo's toy broken. The spirit then flew away with Suneo chased after it. It later noticed Nobita licking his ice cream and took a like to it. As he refused to share his ice cream, the spirit steals it from him and begins to taste, only to be frozen momentary because of the coldness, and drop the ice cream. Unfortunately, some of the ice cream fell on Gian's head and Gian, thinking that Nobita did it, attempts to punch him but the spirit came to rescue by using its wind power to blow Gian away into a nearby trash can. Feeling bad, it then attempted to follow and give back Nobita his ice cream (that fell on the floor) with Nobita running away in disgust with Suneo who witnessed the spirit's power in the distance and followed them.
At Nobita's house, Doraemon is quite surprised in the spirit's appearance and discovered that the spirit is something akin to a "child of typhoon". While they were researching the spirit starts to create a mess in the room, including pulling out Nobita's failed test papers. In an attempt to calm it down, Nobita gave it the name "Fuuko" which means "child of wind" with Doraemon questioning the feminine name choice. When Nobita's mother starts to notice their actions, Doraemon suggests Nobita release Fuuko with the latter suggests the other way and pleads to keep her. Left with no option, Doraemon brought out Adjustable Size Stuffed Toy Camera which Fuko can wear to conceal her identity. After choosing "Dorakokko" as her costume, Fuko then put the costume on and helped Nobita and Doraemon clean up the room. They escape the house before Nobita's mother reaches there with Bamboo Copter, not noticing Suneo on the street looking for her which Suneo doesn't notice them either.
