The level has no secret exit.
The level starts with a screen border featuring Morton throughout most of the level and a lava corridor with some Lava Bubbles, Dry Bones and an elevator which goes down and up. After the elevator, there's a door which ends the lava corridor which leads to another lava corridor! There's a platform with a On-Off switch button in that room. But that's not the only switch you'll encounter, there are several other On-Off switches which you'll use in progressing the level. At the Boss Door, there will be 2 Blarggs guarding it and a box containing a power-up. Take the Boss Door to fight Mecha Mario and Morton. The castle is in the southern part of the Forest map.

Mecha Mario does everything you do, but in the opposite direction. There are 2 blocks in the arena which you can destroy and let him plunge there.
Originates from Super Mario Bros. 3. Morton will occasionally throw Bob-ombs or footballs attempting to hit Mario. To defeat him, just avoid his attacks. Eventually, he will throw a Bob-omb but fails and explodes on his face.
You will need a Cape Mario. At the second room of the level, fly until you reach the platform with an On-Off switch. Leave it On, as the lavafall next to you is gone. Fly again in the spot of the lavafall and you'll reach a warp pipe. Within lies the Orb. Take the door within the room to go to the Boss Path.
Morton's Castle uses a black background at first, but eventually uses a castle background from Super Mario Bros. 3. When fighting Morton Koopa, the background uses graphics from Super Mario World 2: Yoshi's Island.
The music used through this level is "Castle". When fighting Mecha Mario and Morton Koopa, the music used is "Boss Battle", both of which came from Super Mario World.
