For future reference, just tag a candidate then move on. Admins need to check the page's content before any decision is made, so if we see one that has nothing but the tag then we'd need to go all the way back to the previous revision. It's a pain. It isn't good either for any random reader to stumble upon a page only to find an essentially blank entry.
"perfect just the way they are" is highly subjective. According to this thread, the infobox picture you added is lower quality than the one with the blue background. I don't want to start an edit war either, so just leave it like it is.
I know that The Mysterious Force isn't a real thing. It's actually Doofenshmirtz and Perry who make Phineas and Ferb's inventions disappear which is a running joke in the show.(With the exception of the Star Wars special because it takes place during the events of Star Wars Episode IV: A New Hope.)
BTW: Doofenshmirtz' name changes to Darthenshmirtz and Perry the Platypus' name changes to Perry the Rebelpus.
Also: Just like Star Wars Episode IV: A New Hope, The Death Star gets blown up by The Rebels. To be specific Luke Skywalker who's father is a former Jedi turned Sith Lord.(You can go ahead and guess which one.)
