Unless she's actually posted/shared babyfur art, I'm going to air on the side of caution and say that she's being facetious.
The second thing she posted was "kemono friends" which after googling is a videogame/cartoon about little kids who are furries. None of her other tweets looked like genuine shitposts, so I wanted a consensus as to what everyone else made of it. I am going to pass it off as the one time she wanted to tell a joke of twitter, but otherwise it's another thing to make fun of her for.
Now this is a whole other can of worms. How frequently do you stalk her tumblr? It's good to know that she made this when she was a teen, as that explains why most of it is complete gibberish. How she managed to make it up as she went and have it planned out at the same time, I will never figure out. The fact she is planning to reboot it is concerning, because it somewhat jeprodizes my review in it's current state.
