Monkeys vs. Bloons is a map for Bloons TD 4 for the iPhone and iPod. It is extremely hard, probably the hardest, because it has 6 short entrances and 4 exits. Bloons enter from the right and exit at the left.
The player should spend all of their Money on Dart Monkeys and Boomerang Throwers, until some Sun Gods are affordable. Make sure that you have Splodey Darts in order to do this; otherwise you would have low lead popping power.
