The other four, as mentioned above, are Perry themed. “Interview With A Platypus” has the boys making a device to translate what Perry is thinking. “Oh, There You Are Perry” finds Perry or rather Agent P, temporarily reassigned to a new evil genius. “Chez Platypus” has the boys build a trendy Platypus-themed restaurant. And “Perry Lays An Egg,” has the boys and Candice mistakenly believing that Perry has laid an egg.
The bonus features are very cool and include "Dr. D’s Jukebox-Inator;" which lets you cut to one of the Christmas songs; "Christmas Perry-oki" where you can play the movie and follow the bouncing Perry during songs; and a behind-the-scenes look at how the creators write a song. The highlights have to be bonus episode “Doof Side Of The Moon;” letters to Santa where Old St. Nick reveals what Phin, Ferb, and friends have asked for; and “Phineas And Ferb’s Virtual Fireplace. That’s right a new twist on the TV Yule log with a half an hour of an animated fireplace with the cartoons characters popping in from time to time to spread some Christmas cheer and laughter
A Very Perry Christmas is true joy for those who love the show and enjoy its wit, animation, and creatively simple songs. It has wonderful appeal for fans young and old.
