Aim n Drop

Aim n Drop is the twentieth level in Bloons Player Pack 1. In this level, there are two lone bloons at the bottom-right and bottom-left corner, surrounded by Metal Blocks. There are two specific spots where the player has to aim, at minimum power, to pop both bloons:
 * For popping the bloon at the left, the dart needs to be aimed at the ninth Rubber Block, starting from the left;
 * For popping the bloon at the right, the dart needs to be aimed between the eleventh and twelfth Rubber Block, starting from the right.

Trivia

 * It is possible to complete the level by using only two darts.
