First I saw a monster floating in Moo Shu. It was stuck walking against the fence then it walked through it a bit and started to float still its legs moving like walking but it was going up ;P
Then I was at end of shirataki temple and found a space where I can be above averyone :-D It was in the central circle. Way cool :-D
