Here is a video I've found by an animator named AZmaybe 9. Of course it is a growth video involving a young woman growing from normal size to mega size. Over the course of the video she grows bigger and bigger as she gains some revenge on bullies, spends a bit of time with a guy she likes and accidentally causes some destruction. There are some pretty great foot growth moments for those who enjoy that.
Please support AZmaybe 9 and check out his other work.
