If you visit the Grilda and Vilar pages right now, you'll notice there's a small section called 'Search Radius' in the infobox, at the lowest section. That's called a parser row; it's a parser function made to hide a row when there's no data in it.
So go ahead and add the search radius to the other Child Spectrobes, because it's now possible. Any suggestions as to what other hidden rows we could add?
Admins, Template:! is now protected from anonymous editing as it is crucial to the template. Also, all it contains is a pipe (|), so there's not much to see there.
