Palais PomPomRouge Question - how do I get back?

[dlcatftwin]

Seriously, :-) the room below the aforementioned room (18104) has an entrance to go up INTO this room, complete with arrow (as in

go here

), while to enter from above is indeed sheer secret -
I suppose one might call that

2nd chance

; actually it's a 2nd chance entering into Room 1804, but it is a penalty trying to *leave* afterwards.
Just an opinion,
Thanks,
