>>38274484Pikachu's status as a mascot had a serious effect on its design to the extent that the value of the change really can't be measured like this. From the way I see it, Pikachu's current design lends itself to marketing far more effectively in the way it is so easily able to emote and gesture in ways that would just be awkward for the original design if not harder to pull off. Also, having no neck and tiny feet don't make a monster, those are called hamsters.
