User blog comment:Iamnotahacker123/Is Lily really going to be like this when she grow up?/@comment-31789809-20170721061333

I also notice some very minute details, such as the bouncing motion of the hair whenever Lily moves her head, that I've only ever seen in the show and certain fan animators. The problem is that said fan animators have different art styles than the one shown here so we can rule them out. In short, I do believe there is a high possibility that this is from the show and the creators simply took inspiration from the fans for the future form of Lily.
