Phineas and Ferb Christmas Vacation is a Christmas special spun off from the Disney Channel series Phineas and Ferb, scheduled to air on December 6, 2009. It will be premiering on Disney XD, and will then subsequently air on the Disney Channel (debuting December 11th, 2009) and ABC Family as part of the 25 Days of Christmas (the latter marking the first appearance of the show on that network). Series co-founders Dan Povenmire and Jeff "Swampy" Marsh, along with the special's director Zac Moncrief, have announced their hopes that the special will become a holiday classic.
It's Christmas Eve and an excited Phineas and Ferb are working to turn the city of Danville into a giant shimmering thank you card to Santa Claus. Meanwhile, Dr. Doofenshmirtz develops a Naughty-inator, and suddenly the Tri-state area is clouded in naughtiness and kids’ letters to Santa are returned unanswered. Two of Santa's British elves arrive to investigate, but Phineas and Ferb must quickly devise a way to spread holiday cheer, all while Mom and Dad go to the airport to fetch Grandpa and Grandma Fletcher who've just arrived from England. Meanwhile, Candace tries, in a not so covert way, to figure out what’s on Jeremy's Christmas wish list.
