2 Morton's Castle
From the Super Mario Wiki
Morton's Castle is the second castle that Mario comes upon in his escapades in Dinosaur Land during the events of Super Mario World. It is ruled by Morton Koopa Jr. The first part is a hallway with two Thwomps. If the player was to fly through a gap in the ceiling with a feather, the player would find a bonus area. After the Thwimps, there is a conveyor with three Ball n' Chains, and the door to the next room. The next segment has lava pits, three Thwomps, and a Dry Bones.
