Doraemon

Papi, the tiny president of a faraway planet, escapes to Earth to avoid being captured by the military forces that took over. Nobita is making a space movie with Gian and Suneo. After Nobita accidentally destroys the set, both Suneo and Gian do not let him join again. Nobita goes to Doraemon to help him create a space movie. Failed at asking Dekisugi to help (who is asked to join by Gian and Suneo), they instead ask Shizuka for help, who prefers to make a movie about dolls, disappointing Nobita. Shizuka uses her favorite rabbit doll for the filming, but it disappears after she and the others are distracted. After Nobita's mother rediscovers the doll, Doraemon, Nobita, and Shizuka find Papi inside it, who explains that he is the president of Pirika planet, which is currently suppressed by a dictator named General Gilmore. Becoming a top target for Gilmore, Pirika is transported to Earth for safety. He is offered shelter in Shizuka's doll house. Later, Gilmore's top officer, Dorakorule, leads an attack on Gian and Suneo's set. Learning that Dorakorule is spying on anyone who hide Papi, Nobita and his friends hide themselves from the spies (taking form of fireflies) and create a hideout in Shizuka's house, which doubles as a factory for weapon-making. However, the hideout is subsequently raided, Shizuka is kidnapped, and the "Size-Changing Flashlight" (used to shrink Nobita and his friends) is taken, leaving the others stuck at their form. Papi offers himself to be taken in exchange for Shizuka's safety, which Dorakorule accepted. Papi's pet dog, Rokoroko arrives but is too late to save Papi. After explaining about himself, he, Nobita, and his friends go to Pirika to save Papi.
