Phineas and Ferb Christmas Vacation!

"[...]We're actually going to do a Christmas special of Phineas and Ferb."

- Dan Povenmire

An untitled future Christmas special has been announced and is set to be released December 11th, 2009. On Disney XD Germany it'll premiere on December 18th, 2009 as "Phineas und Ferb Xmas Special".

Episode Summary
Phineas and Ferb decorate the Tri-State Area to thank Santa Claus. Doofenshmirtz activates his Naughty-inator and causes much trouble in Danville. Two of Santa’s fairies were sent to Earth to stop him. Meanwhile, Candace tries to find out what’s Jeremy’s biggest wish and finally makes him to write Santa a list of wishes. When Perry beats Doofenshmirtz, the Naughty-inator gets destructed but it’s too late and Santa arrived in Danville.

They always have it Summer vacation though. It they do Christmas vacation, then Summer will have to start all over again.

Songs
This is likely a Season 2 episode, and because it is a special, the lyrics for the theme song will change. The known lyrics as of now are:

Two wondrous weeks of our Christmas vacation

Before New Years and school comes to end it

So the holiday problem for kids of all nations

Is finding a good way to spend it

Following this are montages of doing Christmas activities. Currently, the episode is still in heavy production, as the title has still not even been finalized, and nothing has been given of the episode's plot.
