==Layout==

Star World 4 consists of one long screen, which the player has 300 seconds on the [[Time Limit|Timer]] to complete. There is a [[? Block]] halfway through the level which contains a [[Cape Feather]] if [[Mario]] or [[Luigi]] are big, and a [[Super Mushroom]] if they are small. This level has no [[Dragon Coin]]s in the original version, but the [[Super Mario World: Super Mario Advance 2|remake]] adds Dragon Coins. Like all Star World levels, there are two ways to beat the level.

The player will start next to a red [[Yoshi's Egg|Yoshi Egg]] which will hatch into a red-colored Baby Yoshi once the player gets close to it. If the player has a cape, the player can fly through the entire level. If the player has no cape, they will need to progress to the right while avoiding [[Koopa Troopa]]s and [[Koopa Paratroopa]]s. A little less then halfway through the level is a ? Block with a power-up for the player. There are also a few columns of red Koopa Paratroopas to avoid. Three-quarters of the way through there is a blue [[Unshelled Koopa Troopa|unshelled Koopa]] which will kick a [[Shell]] at the player. The player can also have green [[Yoshi]] eat a Blue Shell and fly through most of the level that way.

===Secret exit===

To find the [[Key]] and [[Keyhole]], the player should already have completed the [[Red Switch Palace]] and [[Green Switch Palace]], however it is possible to jump off the green platform directly after the area with the pipes and float backwards underneath it as well. The player will also need a Shell or cape to hit the ? Block containing the Key next to the Keyhole. To get to the platform where the key and keyhole are, the player should drop down onto the green [[! Block]]s located below the part with the orange pipe and continue right onto the red ! Blocks, then hit the ? Block next to the Keyhole for the Key. This will unlock the level's [[secret exit]], allowing easy access to [[Star World 5]] and to the Star Road leading to the [[Front Door]] of Bowser's Castle in the [[Valley of Bowser]].
