Junction is the 4th Beginner Extra level in Super Monkey Ball 2 (9th in Super Monkey Ball Deluxe), the 10th stage of Under the Ocean in Story Mode (18th in Super Monkey Ball Deluxe), and the 49th Ultimate stage without continues.
This stage has two platforms. Both are long with diamond-shaped holes and areas. The goals are at the end of each. There is no flat, rectangular platform at the start of the green goal platform. The green goal platform is longer than the blue goal platform, and it is more tilted down.
There is a Blue Goal and a Green Goal in this level.
The Blue Goal is on the front platform. To get to it, go forward, and move left and right to avoid the holes. When you reach the end, just roll into the goal.
The Green Goal is on the back platform. Remember to turn around, and be extra careful since you'll be moving faster. The green goal's difficulty is different between Story Mode and Challenge Mode. In Story Mode, players can easily roll onto the platform. But in Challenge Mode, the platform is farther away, resulting in players having to build up momentum to reach it.
