Over the last week while looking though some of the Animaniacs pictures, it appeared the site for a while was having conflicting differences on what the Warner siblings should be when it comes to their species. In the series it self they were ambiguous. They have animal parts such as tails and feet but were never actually animals.
So I went back on close to almost every picture on the site at this point and added the tag Inkblot to their species and even created a short wiki for it.

It's also not just the Warners either. The tag can easily fit certain other characters too that are based on the Silent Era between the 1920's and 1930. Bendy the ink machine Demon is one as well and possibly even Cuphead too.

New tags discussion
Kind of got a little buried but it's a good topic to keep track of for these sorts of things.
