This stage is considered very difficult. It is notorious for being one of the most frustrating levels in Super Monkey Ball 2 and Super Monkey Ball Deluxe. It consists of a platform with domes on it. They are arranged diagonally across the entire platform. There is a banana bunch located right next to the goal.
The blue goal is a only goal in this level. to get to it, jump onto the dome covered platform carefully, and then swerve side-to-side until you make it to the end. Be careful when moving at all times and especially at the end where there are no more domes since it is very easy to lose your balance when transitioning from domes to no domes.
Roll up on the sides of the stage, right then left. Then, go to the rightmost column of domes. Keep your speed. And if you hit it at the right angle, you will be able to hit one a second time, and be able to hit it in the middle column. And if you hit that at the right angle, you will bounce into the goal, also getting the banana bunch.
There is, however, a very easy way of beating Domes. The moment you spawn, do not move, and pause the game. Look at the timer. If it says "59.88" on the timer, hold up before unpausing, and then unpause the game. Run straight forward. You will go straight into the goal. It may seem like you will hit the goal post; you will not, however.
