Alot Going On

 is the sixth level of Bloons Player Pack 1.

Completion
To complete it, the player must pop the Tack Bloon at the top. Then, a chain reaction will start, releasing Pac-Man from the Pac-Man Bloon. Then, it's up to Pac-Man to remove the remaining bloons.

Trivia

 * A decently long chain reaction occurs in this level, hence its name.
