But isn't growing like evolution.
Like in the first image from monkey to a man?
I'll quote:
Keep in mind that "evolution" is the key word. Make your Knuffel evolve. It is not a plant that grows from a seed, not an animal that hatches from an egg, not a magical girl that transforms into something different in the blink of an eye, and not some random dude that changes his clothes to go out with his girlfriend.
In the thread it was emphasized that the evolution shouldn't be only change of clothes. And I think blinking, changing hair length and rising/lowering ears isn't much of a change that I would attribute to evolution.
