Supplies

Supplies is the fifth level in Bloons 2 and is in Popping Fields. It is the first level in Bloons 2 to feature a Bonus Dart Bloon.

Solution
Make sure you hit the Tack Bloon in the middle of the Bonus Dart Bloons, rather than hitting them individually in order to obtain all eight bonus darts at once. Afterwards, simply aim each dart against as many bloons as possible.

For the best score, keep aiming horizontally onto as many bloons as possible.
