Killed him as 55DRK/THF with less than optimal gear. Dropped me to maybe 65% HP. 1/1 on Mycophile Cuffs (45% moon).
To get the Danceshrooms, I went to Ordelle's Caves and killed the Shriekers there in the dew room. These cave Shriekers did not drop Woozyshrooms for me.
However, the Shriekers in Carpenters' Landing do drop Woozyshrooms, but do not seem to drop Danceshrooms.
So to reiterate:
Woozyshroom = Carpenters' Landing
Danceshroom = Ordelle's Caves
Sleepshrooms are dropped by all and can be stolen.
