In this level, two groups of Bloons circle around in an anti-clockwise direction within a metal frame. One must time their shots perfectly to complete this level. It's very easy as the two 'lines' of tack bloons are fairly long. It is also the first Bloons 2 level to have Metal Blocks.
- This level only has Tack Bloons along with metal blocks, making it the only Bloons 2 level without any normal bloons in it.
- One dart is enough to pop one group of tacks, so the player shouldn't have any problems.
