There are at least two known songs. One is "We Wish You a Merry Christmas" and "Christmas Cannot Be Destroyed Not Even by a Naughty-Inator".
Major Monogram contacted Agent P via a screen that popped out of Perry's fedora, directing him not to play the CD, but Dr. Doofenshmirtz had already done so. Heinz realized that Santa was the one who gave the CD to Perry so which is later revealed to be part of a plan to make Phineas's wish to be just like him come true.
- "We Wish You A Merry Christmas"
- "Christmas Cannot Be Destroyed Not Even by a Naughty-Inator"
- One of the song's albums, destroyed the Naughty-inator with the vibrations.
- The message "Santa Claus" actually has an extra "Y", as "A Sal Tuscany". ("Christmas" is in a different font and doesn't contribute to the secret message, even though Doofenshmirtz implies that it does.)
