Anyone else been to that purple tile place with some weird looking owl creature sitting on a bench? Interacting with it sped up the room and I remember there was an effect that made it when you interact with the owl the room went crazy, though I forgot...
But I do remember it was accessible through the Flying Fish World(keep going in and out from the hall that leads to Urotsuki's dream scene until you get a purple background and proceed through the fence)
