Super Mario World improvement

About

Mario has a dream of a staircase leading to a mysterious door to a mysterious place. A voice identifies the world as the dreamland of Subcon, and asks for Mario's help in defeating the villainous frog named Wart, a tyrant who has cursed Subcon and its people. Mario suddenly awakes and decides to tell Luigi, Toad, and Princess Toadstool, who all report experiencing the same dream. The group goes on a picnic, but discovers a cave with a long staircase. Through a door at the top, they are transported to Subcon, revealing their dreams to have been real. After defeating Wart, the people of Subcon are freed and everyone celebrates. Mario suddenly awakes in his bed, unsure if these events were a dream. He soon goes back to sleep.
