Secret Exit
The path to the secret exit (which leads to World 5-A) starts with a small opening in the ceiling near the end of the first room, before the first door, above the right extent of the second swinging platform. An invisible block containing a Beanstalk is located directly below it. Alternately, Raccoon Mario can fly up through the opening. Through the opening and up a flight of stairs, a door leads to another room with a series of swinging platforms and ropes. At the end of this room is a yellow ? switch and a Big Boo. When the player hits the switch, four doors appear. The correct door is at the top-right, behind the Big Boo which must be lured out of the way; there is no time limit to reach the door.
