Detour (or Detours in Banana Mania's Story Mode) is the 18th Expert stage in Super Monkey Ball 2 and the 37th Expert stage in Super Monkey Ball Deluxe. It also appears as the 147th Ultimate stage with continues and the 187th without continues.
This stage consists of a long, straight platform that leads perpendicularly to a steeply inclined platform, on which a wormhole is situated at both ends of it. There is a blue goal on the left, higher up on the inclined platform. There is also a green goal located on a smaller inclined platform to the right and behind the main inclined platform. There are two banana bunches on that green goal platform.
When you approach the inclined platform, bear right, and roll into the wormhole, which will teleport you to the top of the incline. Position yourself in-line with the goal, and roll into it. If you miss it, you can roll back down into the wormhole and try again.
Roll into the wormhole. Upon teleportation, bear to the left of the platform, and jump off the ramp. Position yourself in the air, and bounce into the goal.
