Just managed to record the thirty-second trailer, one which included an aerial view of the Robot Riot sequence.

The only characters I caught were: Phineas - Riding the 'Canderemy' robot dog with Perry by his side Ferb - Riding a mechanical bull Isabella - Riding a (flying?) unicorn/horse Baljeet - Using the Beak Suit Buford - Controlling the bottom half of the mechanical platypus Fireside Girls - Controlling various projects, i.e. The Car Wash and monster trucks Neighborhood kids - Same as Fireside Girls (various projects)

There was absolutely no indication of the alternate characters. If that's the case - and 'Don't Block Me' is, in fact, being truthful - looks like Isabella is headed to the second dimension.
