For Eevee I don't have much plans of making her to be a giantess, but other pokemons I do.
For the growth quotes stated here, it was supposed to meant height growth, but it looks like the description fails to do so. I'll make sure the text that she will always have growth every level in some parts of her body clearly, and not state any parts that did not grow to distract from the pretty new growth. Thanks for the feedback.
