The film was followed by the third film of the series directed by Satyajit Rays son, Sandip Ray.
Goopy and Bagha are bored with their lives as crown princes of Shundi and Halla.

But little do they know of the machinations of Hirok Raja Utpal Dutt. The king is a tyrant. Diamonds and riches get pent up in his treasuries, while his subjects starve and suffer. Those who protest are taken care of in the Jantarmantar, a chamber for brainwashing devised by the scientist Santosh Dutta, who the king mocks calling as Gobeshok Gobochondro Gyanotirtho Gyanorotno Gyanambudhi Gyanochuramoni. His ministers are mere puppets. The only enemy the king has in his land is Udayan Pandit Soumitra Chatterjee. He is a school teacher and, more than that, he is a believer of values. The king forcefully closes his school down. Udayan flees to hide in the mountains.Meanwhile, Goopy and Bagha are on their way to Hirok Rajya. By coincidence, they meet Udayan, who intimates them of the kings true nature. The two impress Udayan with their magical powers, who plans to use them against the tyrant. Goopy and Bagha agree. The duo then head into Hirok Rajya, where they are welcomed with grandeur. They entertain the rogue king,fooling him into believing that they think he is great. They rob the treasury which was guarded by a tiger using their magical music, for bribing the guards. ........
