#ur so right holy shit
Isabella speaks fluent spanish and pretty good yiddish (shes a bit less practised in that) as well as english
Baljeet speaks hindi natively and english fluently. He takes spanish in school and is pretty good at it (but then what you can actually learn of second languages in school is limited). Beyond that he’s got nothing though, since he focused on science and maths too much to want to learn another
Buford speaks dutch, latin, and french fluently and had pretty damn good spanish, norwegian and greek. He’s able to pick up languages very quickly and by ear
Ferb speaks fluent dolphin, martian, japanese and any language that will help the plot
Phineas cant pronounce ‘gracias’ correctly
