He is the president of Pirika, a small planet in outer space, and has come to Earth to escape the rebels. Doraemon and his friends are puzzled by Papi’s small size, but as they play together using the secret tool “Small Light”, they gradually become friends. However, a whale-shaped space battleship comes to earth and attacks Doraemon, Nobita and the others in order to capture Papi. Feeling responsible for getting everyone involved, Papi tries to stand up to the rebels. Doraemon and his friends leave for the planet Pirika to protect their dear friend and his home.
