Theory about how Purple aged

So in AvM S3 we learn about Purple's backstory and we see him age from a baby to an adult, but this was contradicted in AvA 11 where we learn about how animations are created and how they don't age and remain the same forever and we see adult Purple and his parents during the Disappearance. But, what if animations could age by being in a new animation that their creator posts on the internet. So what I'm saying is that maybe the creator of Purple made a series of animations where he grows in each one of them.
