So we currently have... 14 doors in the castle presently and they lead to different worlds.
First row we have: WALL-E, Moana, Ratatouille...
Second row we have: Toy Story, Frozen, Lion King...
Third row we have: Monsters Inc. Beauty and the Beast, Mulan...
Fourth row we have: Lady and the Tramp, Inside Out, Alice in Wonderland, Aladdin, Hercules...
... But then there's these other areas roped off with a total of 16 doors which presently don't go anywhere. So that's 30 doors altogether, just that 16 of them are not in use. Whether they intend on doing anything with them, I don't know! Like, the doors really could mean nothing, because I know we have characters from, like, Tangled(Mother Gothel, Rapunzel and Flynn), and they don't have any doors that lead off into their respective realms.
... But we're looking at, like... 65 Franchises so far -- which yes, the Black Cauldron is featured among them. Among the others that stick out(to me at least) are: Dinosaur, The Great Mouse Detective, and Atlantis.
And, by god they have very little stuff in the game that actually represents those franchises -- both Dinosaur and The Black Cauldron have one piece of furniture that reference the series. And that's the Cauldron itself, and Aladar's egg.
Um... Sleepy Hollow's got the same problem too(one statue of the Headless Horseman).
But... Yeah, like on one hand: the doors really could mean nothing. Because we have characters in the game who's realms aren't represented on these doors(Tangled for instance.)
But man, I am... Ehhhhhhhhh... I'm grasping at straws and drying to hold out on hope that The Black Cauldron gets more representation beyond just one piece of furniture that was tied to an event way back whenever that may or may not reappear again. Like, surely they have to do more. It makes no sense to have this game deal with, like, forgetting and the forgotten, then not do anything with the one thing that's almost always getting the short end of the stick. 😩
