I'm going to assume that by "add all the data around the monsters" you're referring to my placing the single entries in dual-column list format. There's no reason for it other than improving the general look of the page by keeping entries left-aligned. It's not NECESSARY, no, but it does make things look better and is therefore justified in my opinion.

The page is already huge as it is; removing those dual-column lists isn't going to significantly improve the page's load time, and most of the categories that currently only have one entry are just lacking data at the moment (like the Snake category only having one snake in it right now when there are over a dozen distinct types that could be listed later on). Putting the list format in now saves time later and makes it easier for those who don't know much about wiki formatting.
