Phineas and Ferb is my favorite television series. I really like how it's rated TV-G and they decided to put a platypus in it! I also like the idea of a spy platypus! Really cool.
My favorite part is the spy parts with Perry and Heinz. I really like episodes when the P&H plot combines with the P&F plot. That explains why I like Phineas and Ferb: Across The Second Dimension so much.
