Princess Doremi loves to sing and dance, and her home, Doremifa Castle, reflects that joy until Baikinman and his companions work their mischief on it. Their villainy turns the castle into a gloomy haunted house now called Baikin Doremifa Castle. Naganegiman is named in the title alongside the princess in this comedic fantasy film from the Sore Ike! Anpanman franchise, released in 2003. It screened as a double feature alongside Sore Ike! Anpanman: Ruby no Negai.
