I just added it for 1 character that transforms into something else. It was left in the future tags so I said why not put it in since there will also be more in the next update (If I have enough time, I really hope so because I love those kinds of things).
The pregnancy is still far away since there is a lot of content planed before. I'm glad you're keeping an eye for now and also glad you like the art.
It already has some, not too many but enough to just give it a go I think. There are more in plan and I'm also looking to get some more experienced help with those since I'm really struggling with animating and is not as lively as I want it to be.
