Eiga Doraemon Nobita no Ritoru Sutâ Wôzu 2021

During summer vacation, Nobita picks up a small rocket containing Papi, the president of Planet Pirika, who is fleeing a rebel army led by General Gilmore and his agent Dorakoruru. Doraemon and the others befriend Papi and use the "Small Light" to shrink themselves and play with him, deepening their bond. When Papi's location is discovered, they travel to Pirika to help the Freedom Alliance resist the dictatorship. Together, they defeat Dorakoruru, stop Gilmore, and restore peace again to Pirika. Back on Earth, they screen their finished space war film, hinting that it was based off of their real adventure.
