Phineas & Ferb: Across The Second Dimension has just released their first movie this month (did you watch?). However, Phineas & Ferb: Across The Second Dimension (aff) Wii Game is the followup to that. The game allows you to play your favorite characters (Phineas, Ferb, Agent P, Agent T, etc). There are many worlds you will have to make your way through (including gelatin, bouncy balloons, old school cartoons, etc). You also get to use very cool weapons like the carbonator, ninja glove, and jetpack.
I have to admit that this is a pretty fun game. I love the drop-in/drop-out two-player mode (Madison can play by herself or with one of us), and even though its for ten and up, Madison had no problems with it (she's 7). You can also collect new items and unlock new playable characters as you defeat enemies and make progress in the game.
Phineas & Ferb: Across The Second Dimension is a great followup to the movie and is a must have for all Phineas & Ferb fans!
