I've said many times before one of the things I love about toon women, Frankie especially, is they hold such admirable sets of values and morals and they are not so constantlyu tarnished by use of drugs and overly sexual flirtacious nature.
Frankie is a clean, good hearted, albeit a cranky lady (just like the song says

) who puts the world before herself and works a tireless, endless and as Cass said, THANKLESS job by cleaning, nursing, scrubbing, and basically making Foster's run smoothly 24/7.
She's a sweet person who clearly has alot of love to give and would make a loving girlfriend to any guy lucky enough to see what Frankie has to offer. I love the fact she can be just as wacky and crazy as the other Fosters crew. Just look at how she acted in "Big Cheese" "Cookie dough" and "World wide wabbit".
