i'm considering uploading some fanart from Rusty Lake, however i found a problem: there may or may not be two separate characters named "Mr. Rabbit" in the series, one with white fur, one with brown
the fandom wiki seems to be treating them as one and the same, however people in the article's comments can be found arguing whether the two Mr. Rabbits are indeed the same or not
what would be the best way to disambiguate them? "first appearance" doesn't seem to work, since both the white rabbit and the brown rabbit apparently appeared first in Rusty Lake Hotel, with the white rabbit being more of an easter egg (notably, the achievement 'Watch Closely!' calls him "Mr. Rabbit's soul", but in Cube Escape: Birthday he's simply "Mr. Rabbit"). alternatively, there could be something like mr._rabbit_(brown)_(rusty_lake) and mr._rabbit_(white)_(rusty_lake), but i'm not sure how to feel about that option, making it sound more like it's certain those are two versions of the same character
any other ideas?
