Something easy/glitchy xD
It's just an invisible platform that moves from pipe A to pipe B in one frame. If you're on it, you get teleported. Once the platform is buried inside the pipe, you don't stand on it anymore and you don't keep teleporting again and again. Unless you enter the pipe again.
EDIT:
As a request, there's a new Phantom Ganon Room version. It features both Wind Waker and OoT Phantoms.

EDIT 2:
Progress in another stage I left unfinished, like Melee FD and Mushroom 64. I bet somebody is gonna be hyped with this:
*VIDEO OF FOURSIDE*
Still lot of work to do. Still, it's something
I am so overly excited for a proper Fourside import. I am also excited for any past stage, including but not limited to Yoshi's Story, Melee Final Destination, Mute City and Venom. I love your work, Mewtwo2000. Keep it up. You're the man.
