Treacherous Twister is a level in the Wild West World area of DK: King of Swing. It takes place in a canyon during a vicious tornado. The wind created by the tornado can push Donkey Kong (or Diddy Kong in Diddy mode) to the left or right quickly if he is not holding onto a peg. If it does blow him off the screen, he is forced around the tornado, being viewed through the background, and dropped into a lower part of the level, forcing him to climb up again. The wind is not the only thing the impends in the Kong's progress: there are also Kritters on some of the peg boards in the level that can push him away from the pegs. Other items in this level include barrels, Barrel Cannons, and, for the first time, groups of pegs that move in circles.
At the beginning of the level, a few peg boards can be seen above, with some of them having bananas on them. A peg board with a Kritter climbing along it is above the first five boards, and a second Kritter is on another board just ahead of a small peg board after this. A blue peg board can be spotted higher in the air, being followed by some smaller boards that are placed along a diagonal path. A small space is between each of them, and they all bear bananas. Two larger peg boards are above from here, with a Kritter on the second of them. Parallel to the board below this is a smaller board with a barrel above it, which contains a Crystal Coconut. If Donkey Kong jumps above each of these pegs and floats to the left, he can reach a Barrel Cannon that shoots him into the second area of the level.
In this area, there are more peg boards leading upwards being shook by the heavy winds. A space is between the second and third board, so the Kong must be careful not to blow away as he jumps across. After the third peg board, the ape can find a group of single pegs that are in a snowflake shape. The pegs move in a circle and stop repeatedly. Two additional peg boards are above here, and they are spaced up to make the ape more likely to blow away. If he journeys to the next few peg boards after these, he can notice three groups of pegs forming the shapes of circles parallel to him. The circles of pegs spin and then stop repeatedly, and bananas are placed all along the left side of them. Another rotating, snowflake-shaped formation of pegs is after the section of small, spaced out peg boards. There is a small, blue board of pegs above this formation of single pegs that has some more pegs placed high above it. When they are reached and climbed up, Donkey Kong can find another formation of pegs that create the shape of a circle. To the left of them is a DK Coin. If he jumps from the spinning formation of pegs, he can reach a solid ledge with an exit sign on it. If he lands next to the sign, the level is completed.
