Instructions
Star World 1
Enter Star World 1 and grab the mushroom power up. Drop into the hole and land on a series of yellow blocks.
Move as far to the right as the stage will allow and spin jump through the blocks below. Descend past the Dragon Coin and go through the hole on the right. Continue to hug the right wall and spin attack to move farther down.
When you reach solid ground, jump onto the yellow key and grab it with the Y button. With the key in hand, the adjacent keyhole will enlarge and swallow Mario. This marks the end of Star World 1.
Star World 2
Begin Star World 2 and swim to the right while avoiding unfriendly fish. Proceed forward until you reach a green pipe.
Swim beneath the warp and proceed to the right. Repeatedly tap the jump button to keep Mario from drowning.
Arrive at the key and use it on the exit to finish the level.
Star World 3
Equip a feather before heading to Star World 3. Begin the stage, and fly to the top of the screen (give Mario a running start and jump), and ascend through the stone passageway.
Jump beneath the question mark block to the left.
Grab the key that falls out and bring it to the exit off to the right to complete the stage.
Star World 4
Start Star World 4 after you have finished all Switch Palaces and grab the red baby Yoshi to your right. Feed him Koopa Troopas until he becomes a full-sized dinosaur. Ride Yoshi to the right and jump to avoid the stage's pitfalls.
Dive into enemy barriers with Yoshi. Mario doesn't take damage while riding Yoshi, but the two become separated upon enemy contact. Retrieve your pet before he falls into a pit and proceed to the right.
Arrive at a series of pipes and stone blocks and take the low road. A path of brightly colored exclamation mark blocks will lead you to the stage key and exit. Use the cape so you can whip the question mark block on the ground for the key.
Star World 5
Enter Star World 5 equipped with a cape. As the level begins, gain some running momentum using the first falling platform and fly to the top of the screen. Proceed to the right of the stage while maintaining a high altitude.
Fly above the descending pipes and land on the stone platform. Although you can no longer see Mario, proceed forward and pass by the stage exit below. When the platform stops, fall to the dotted mushroom platform below and take out the Spinies with your cape.
Gain some running momentum and fly up while staying to the left of the yellow pipes. Land in the small stone alcove, grab the key, and exit the final stage of Star Road.
