Dean's baby has been separated from the boys and needs to travel to all of the cities the boys have been to (in no particular order) to try and find them. It especially wants to travel to Lawrence Kansas, Stull Cemetery in Stull Kansas, and eventually Canisbay Scotland before returning back home to Kansas. Here is a list of the cities the boys have been to. (This list is up to Season 5, more will be added soon and visited cities will be crossed off).
