It's more of a Mavpole setup, but whatever. First, you wanna do fast accel first frame entering the pipe. The rest can be played the same, until the pipe. At this point, you'll want to do 2 frames of left in a specific spot in mid-air. After this, you'll want to press left, and then press A for 9 frames, on a specific part of the top staircase. For 3 of those frames, you still wanna be holding left. For the rest, go to right. Then, finally, do D50 inputs.
