Between the White and Black Void

"Some people say that the Black Void and the White Void are two different dimensions. But they are actually connected." -Description

The "Between the White and Black Void" is a Intermediate Track unlocked at the same rank as you unlock Intermediate Tracks.

Appearance
Because of the appearance, it shows the area between the White and Black Voids.

The entrance starts from the bottom left area of the map, and the bloons go to the middle of the track, where they enter the White Void and then, the bloons will exit at the top right.

The Color Change Effect
This applies to the black and white bloons only. Zebra Bloons aren't effected.

If a White Boon shows up on the Black Void, it will turn into a Black Bloon. And if that Black Bloon goes to the White Void, it will change into a White Bloon. The same effect applies if this track is played in Reverse. And Vice Versa.

Trivia

 * This map shows that the White Void and the Black Void are connected.
