Kip. 38: Magic Dragon
As they stroll through a town, Sinbad, Ali Baba and Aladdin are addressed by an old snake charmer with a magic orb who asks them to look for his missing twin brother. Agreeing to help, they find the brother, who claims he was bitten by a snake and needs a certain herb to be cured. But as they collect that herb, the old man suddenly traps them in a pit. He reveals himself as Satajit, the evil sorcerer whom Sinbad has crossed so many times, and turns a snake into a dragon with the orb to kill them. Sinbad and his friends discover that the dragon fears the herb thex have collected, and use the herbs and Ali Bab's rope to make it carrying them out of the pit. Sinbad attacks Satajit, trapping him in the pit and breaking his orb, which causes the dragon to turn back into a snake. (Source: Wikipedia)
