I don't get it why Thomas is never at these things.. I mean he voices Ferb and although he doesn't have that many lines, he's still one of the main characters and his name is in the title... but anyway.. :)
Maybe because he didn't recorded his voice in studio with all actors. Creators sent the episode to Thomas in UK, where Ferb voiced with somebody else, and he just re-voiced dialogs.
I've been googling and i saw a picture of Vincent Martella AND Thomas Sangster together at a Phineas and Ferb premiere, i guess Thomas does care for his character
Every phineas and ferb catch phrase Hey ferb I know what were gonna do today ... Whatcha doin Hey dinner bell Krrrrrrrr Morning agent p CURSE YOU PERRY THE PLATYPUS
"Aren't you a little too young to (insert)"? "Moooom!! Phineas and Ferb are (insert)!!" "Momomomomomomoooooom!! You gotta see this!!!!" "Yes, yes I(we) am(are)"
You know instead of making big costumes of Phineas and Ferb (They are creepy as hell) Why not look like real life versions. I mean The characters of Gravity Falls don't have creepy big headed costumes. Why do P&F have them? It'll be easier!
