I looked up on the wikipedia (wikipedia.org)
It says P&F Across the 2nd Dimension release date is June 24, 2011????????
This is the Plot: Phineas and Ferb finally discover that their pet platypus, Perry, is a secret agent who battles the forces of evil almost every day. The boys team up with Perry on an adventure through a parallel universe where they must ultimately thwart the disastrous plans of a even bigger threat than dimwitted Dr. Doofenshmirtz: a parallel Doofenshmirtz, who, unlike his counterpart, is a truly evil genius with no goofy side or soft spot.
