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. Yoshi needs to go to every room to get the Number balls. Then Yoshi has to go a room that yoshi can drop off his Number balls at but the center of the room is blocked off with a rock. After putting at the Number balls at the right place the rock falls witch leads to a door. The door leads to the goal.

The Number Ball colors and numbers are as follows;

- 1 = red - 2 = green - 3 = yellow - 4 = purple - 5 = blue

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. Fleepers, Ball and Chains, and Piranha Plants are some of the many enemies encountered in this level.
