So apparently I lied

And it's sad, because quality was the qualifier for the show's massive success the first go around: Its charm and quirkiness was made more appealing by its intelligence and irreverence. And now, the ability of its makers to imagine/execute any version of this show without the anchor of nostalgia has made it reverent. A slave to what's most popular, instead of a servant of quality.

Hmmmmmmm lemme think about it...

Ferb is a foodie and a glutton (but this is kinda supported by the source material?)

Phineas is a manic pixie dream girl (listen this has been on my mind for a while and I think it needs to be addressed.)

Isabella has issues about needing attention and recognition and to over-achieve stemming from an emotionally negligent relationship with a distant father that bleeds over into her expectations for other important figures in her life including and maybe especially her crush.

Linda has a small fortune that she's sitting on and she's rich-people-friends with Charlene.

Lawrence likes port and sherry.

Isabella likes snickerdoodles best.

Ferb likes peanut-butter chocolate chip cookies best, but also gingersnaps and shortbread biscuits with his tea.

Buford likes all cookies equally expect for anything with coconut or toffee, and actually doesn't like snickerdoodles at all.

Baljeet would prefer salty snacks over sweet cookies.

Phineas likes chocolate chip cookies best, and actually really especially likes oatmeal chocolate chip.

If you ask Candace she'll say she has no opinion, but her favorite is chocolate chip hands down. She'll dunk them in milk.

Candace's periods are very regular and only mildly painful...... Idk why I have this headcanon except that she has the confidence to wear white skirts and I don't think it'd be fair to imply that any modicum of her high-strung-ness or grouchy behavior should be blamed on hormonal shifts. That would feel kinda wrong?

Vanessa doesn't know who she is. Goth is a culture she feels comfortable in, but it's mostly still performative. Candace has a better understanding of herself than Vanessa.

Stacy had the best understanding of herself, she's actually really solid on her identity because she's just really open to personal change and whatever opportunities may come.

Linda's sister (forget her name) and her new husband Captain Bob(?)Webber never have children together. In fact one or both of them gets the operation done so that it never happens even accidentally. This leaves the Fletcher cousins as the only cousins for Phineas, Ferb and Candace.

"Phineas is a manic pixie dream girl"

He's full of wacky quirks and playfulness.

He's "energetic" and "high on life".

He has colourful hair.

He drags other, less enthusiastic people into his antics in an effort to show them the good things in life.

He's prone to making long, enthusiastic monologues about how life is awesome and person(s) have many reasons to be happy.

He's most often delegated to the role of someone whose sole purpose seems to be making someone else's life happier and more fun.

Phineas is excluded from what's oft considered the male equivalent of this categorization; a "manic pixie dream guy", because this distinction comes with the caveat of the dream guy in question obtaining character development, which the "manic pixie dream girl" is more commonly exempt from.
