I feel like buford has a shitpost blog on tumblr
Isabella too
Both baljeet and ferb have very fancy, nice looking blogs only baljeets posts actually match his theme while ferb is one of those people who answers asks like 'what state do you live in?' with 'look behind you :)' and gets 10,000 notes
Baljeet has a sideblog where he just talks about maths and accepts asks asking for help on their homework and
Phineas has a sideblog where he posts pictures of his and ferbs inventions except they're always either massively blurry and show basically nothing, only of him and his friends having fun with a limited view of what they're actually riding/doing or he has his thumb over the lens
