Editing Six-Face Sal's Fort

'''Six-Face Sal's Fort''' is the fourth [[level]] of [[World 4 (YIDS)|World 4]] in the game ''[[Yoshi's Island DS]]''. Like all of the fourth levels of worlds in ''Yoshi's Island DS'' (and the original ''[[Super Mario World 2: Yoshi's Island]]''), it is a [[fortress]]-type level with a [[boss]], [[Six-Face Sal]], who is a wooden wheel with six rotating faces on it, at the end. It marks the proper introduction of [[Number Ball]]s, not counting the extra levels. Yoshi must find the Number Balls and throw them at the holder to open up doors and find new areas. Upon defeating Sal and its fort, [[Yoshi (species)|Yoshi]] and the [[babies]] move on to World 4-5, where [[Baby Bowser]] is met. This level's playable Yoshi is the Yellow Yoshi.

Yellow Yoshi starts the level in a castle with some moving platforms and enemies, with a Number Ball nearby. After avoiding some maces and lifting a crate by standing on a moving platform, Yellow Yoshi reaches the next area which starts with a middle ring and three holes for the Number Balls. The player needs to go down to the next area to get the first ball, and then head back and take a moving platform upwards. This transports Yellow Yoshi to an area with the second Number Ball. He must now exit the area and go to the right, where the third Number Ball is eventually found. The player must return to the area with holes, and put each Number Ball into its corresponding hole. This makes a nearby door open. It leads to a moving platform and another door where a [[Stork Stop]] and the boss door are found. The door houses [[Six-Face Sal]], who can be defeated by throwing eggs at his pink face.
