The Great Escape from the Thank You Very Much Prison

Nobita skips his summer homework and uses Doraemon’s What-If Phone Booth to create a world where nobody scolds—so happy Nobita stays lazy while Doraemon discovers scolding has been outlawed in the future. When Doraemon and a robot teacher, Ikkoku, are arrested for a temper incident, they’re sent to an offshore prison run by the diamond-obsessed Majime and superintendent Donpa. Nobita, Dorami and friends sneak into the past/present prison using Doraemon’s spare 4D pocket, free Doraemon and the inmates, and withstand ant-robot guards and Majime’s giant statue. With gadgets like the Genius Helmet and Technical Gloves, they defeat Majime, restore the stolen What-If Phone Booth, and return everything to normal—just in time to celebrate Doraemon’s birthday.
