He was only a corn plant for about a chapter or two. Its not long enough to be classed as a species change. Its like with Percy, he was only a guinea pig for not even half a chapter. It doesn't say that he was formerly a guinea pig on there. I think that it's required that the change be significant, or vital to plot. Nico becoming a corn plant wasn't exactly relevant or for a significant amount of time.
