Number Ball Special

Number Ball Special is an unlockable level in Yoshi's Island DS. It is the third appearance of the White Yoshi in Yoshi's Island DS. It is also the first level containing Number Balls (unless the Player has unlocked it after playing Find the Number Ball!). Unlike A Light in the Dark, Baby Wario is playable here as well. The level starts out with Yoshi above ground with a pipe leading underground. The players need to use a certain baby for each area. Once the player collects all five Number Balls, they can go onto the goal ring, completing the level.
