Phineas and Ferb are up to unbelievable shenanigans like never before! The boys take hockey to the extreme with Hockey Z-9, put their own special touches on the New Year’s Eve ball drop, and accidentally turn Candace into a fly. Perry the Platypus, aka Agent P, has much bigger problems than just Dr. Doofenshmirtz. He teams up with a former partner to stop a hijacked train and comes face to face with an Australian platypus hunter set out on destroying him!
