So recently while playing my Critical Level 1 game mode which I had completed last night ^w^ I used the Twilight Town Mansion to level Sora's Final Form up a little and for some reason I felt like the mansion was worth taking a look at in a little bit of detail. One of the first things I had checked were the painting which I found many of them were hard to make out, except for one that looked very very much like the Tea Party Garden from Kingdom Hearts 1 in Wonderland. It's made me wonder if the other painting may be other places from different worlds and if whoever owned the mansion before had traveled to these worlds themselves.
Also, sorry about the image of the painting for some reason it's been flipped around ;;
