I've read that the dick had originally been sized more proportionately to the figure, but at some point it was merged with a large circular belly button, increasing its size/length. I wonder whether that is the result the article is referring to, or whether there was an initial project to add a penis to the figure, followed by a distinct "this penis needs to be longer" revision later on.
