Kick the conductor 8 times, walk into him until he jumps, kick him as he flies up, weave under him, and jump into the air Go into ball mode and hang out in the air until he kicks Piku

And from the current wr holder, Frostbyte1: "I do the [strat mentioned above]. I even have a video made showcasing it. After that it really is just muscle memory and practice. Although I would say the unseen evil here is having the game eat your inputs by being to quick. I've definitely messed it up a lot because I pressed jump too soon before ending the dialogue. It's a double-edged sword though because if you aren't quick enough to cancel the text and jump then the conductor will have fallen too much and will be in an unfavourable position"
