The biggest change is the navigation column itself-- instead of having lots of different options, the column is organized solely by pet family, so to see information, for instance, about all the gorilla pets, you click "gorilla." Easy enough. But those old options aren't lost-- in fact, they're easier to browse, because since Mania's put all the info into a real database, that database is now searchable by criteria. Want to see all the pets that can Prowl, or every pet that eats fruit available in your level range? Plug your queries into the form and get your own customized list. Nice changes, and we're told we can expect more to come.
