Chronologically, the "real" Bowsette is the transformed version as that was the original way she spawned.On that note: what is the difference, if any, between the "real" Bowsette (painting) and the transformation (fairy witch), aside from how the game spawns them?
The painting thing came much later (Halloween of last year if I'm not mistaken) as an alternative. AFAIK the two are identical in behavior.
Oh, and for your previous post:
Did you make sure to enter every other painting in the mansion first? Bowsette painting remains locked until then.did I miss some requirement or did something else entirely made it go kaput.
Idk if the cat burglar painting counts as that's the most recent addition. There may very well be bugs regarding that one but I personally can't be fucked to find out.
