Fish in Rubber Barrel

Fish in Rubber Barrel is the 10th level in Bloons 2 Mobile. This level is located in the Popping Fields. It is exclusive to the mobile version of Bloons 2, replacing Out of the Blocks. The name of the level is taken from the phrase "like shooting fish in a barrel," meaning that something is very easy.

In the level, the Bloons are enclosed from three sides in a rubber "barrel," making all darts bounce around. The player should aim for the Bonus Dart Bloons and the Triple Dart Bloon as they only get one dart to begin with. Then, the player should focus on hitting the other Bloons by making large bounces to maximize the amount of Bloons each dart can hit.
