Phineas and Ferb: Christmas Vacation

It's the night before Christmas, and Phineas, Ferb, and the rest of their friends are filled with holiday cheer. But little do they know that every kid in Danville is on the naughty list, thanks to the evil Dr. Doofenshmirtz and his latest creation-the Naughty-inator! Luckily, Phineas (with the secret help of Agent P) convinces Santa's elves that it's all just a silly mistake, and Christmas is saved for everyone!
