When Kim opens the front door after we hear Ron hit it, there is no doorknob on the outside of it (the side Ron slides down).
When Wade is informing Kim that Ron went to stop Drakken, there is one point where we see him on the screen but his voice is not filtered.
While trudging through the Amazon looking for Ron, Kim has the Kimmunicator strapped to her wrist, checking on the pods position, however in the scene immmediately after, while wading through the water, it's no longer on her wrist.
When the new Kimmunicator is delivered, it's originally in a box, judging by the package. But Kim tears away the brown paper to reveal the Kimmunicator, without opening any box. Originally the package was bigger than the 'municator, so where'd the box go?
When Drakken says "It's just not the same when I rant to myself" the circles under his eyes aren't filled in.
Watch when Ron jumps up onto the wall of Drakken's fortress. Originally, it looks like he goes up a good 6 feet or so. But when it shows him full-length again, after the door swings open, it looks like he's just a few inches off the ground.
Wade said the Kimmunicator was destroyed in the stratosphere...but it wasn't...it was destroyed when Drakken stepped on it, BEFORE the liftoff even occured!
There's a small mistake in this episode's themesong opener. During the line "You can't stop me" (visual: surrounded by the Bebe robots), Kim's hair has a lighter outline to it, which it loses a second later.
Delivery Man: Package for Kim Possible.
Kim: That's me. Thank you. Merry Christmas
Delivery Man: It would be if I didn't have to work.
Ron: Thanks for the ride, Captain Louis.
Captain Louis: It's the least I can do after you saved this old tub from sinking. Hold on, Kim Possible saved my tub from sinking.
Ron: Well, that's right, and I'm always there. You know, Kim and...
Captain Louis: There was a fellow with her busting my radio, used my navigational charge for a napkin. What was his name? Ron something.
Ron: Yes, yes, yes, Ron Something. Sadly, uh, Mr. Something didn't work out. We had to let him go. So, I'll see ya, see ya!
Drakken: (to Ron) How's that, Mr. Smarty Boots?
Ron: (calling) Yes, information? I'd like the number for nine-one-one, immediately please!
Ron: Dude, that's a cell phone!
Drakken: Yes, It should leave quite a welt.
Ron: Not for throwing, for calling! Calling for help!
Drakken: To all people, far and near. . .
Drakken & Ron: Snowman Hank brought holiday cheer.
Kim: This is. . . this is. . . I don't know what this is.
Nana: Isn't that Kimberly Anne's arch foe?
Dr. Possible: 'Tis the season.
Wade: Then who's going to stop Drakken?
Dr Drakken: I can tell you this, in the little TV in my heart, Snowman Hank will play forever.

"A Ringlin' Jinglin' Christmas": Written and Arranged by Randy Petersen and Kevin Quinn
A Christmas Carol
If you look closely, the sign that is outside Dr. Drakken's hideout says "Bah Humbug", a sentence used often by Ebaneezer Scrooge, the main character in Charles Dickens book A Christmas Carol.
A Charlie Brown Christmas:
Drakken: All I want is what's coming to me. All I want is my fair share.
These are the exact words Lucy said to Charlie Brown in the Charlie Brown special A Charlie Brown Christmas.
A Nightmare Before Christmas:
The shot of Ron and Dr. Drakken after they land on earth again has them on top of a peculiar cliff. This cliff resembles the same shape as the one Jack Skeleton stands on in A Nightmare Before Christmas.
This is the title of an episode of Lizzie McGuire.
A Simple Plan:
When Kim looks into the third escape pod, a flock of crows fly out at her. This scene is similar to one from the movie A Simple Plan where Bill Paxton opens the door of a crashed airplane, only to have a flock of crows fly out and attack him. Gary Cole (The voice of Mr. Dr. Possible) also had a role in the movie as the dead pilot's brother.
The shot of Ron and Rufus in the garbage escape pod, looking out at the exploding Drak Force 1, is similar to C3-PO and R2-D2 looking out at a Star Destroyer and the Rebel Blockade Runner that they recently escaped from, in Star Wars: Episode IV. The pods in both Star Wars and KP also show a resemblance.
Jim/Tim: We just re-routed the Middleton power grid... ... so we wouldn't blow out the whole town like last year
A reference to the National Lampoon film Christmas Vacation where the over-zealous Clark Grizwold decorates his home with 25,000 lights, which results in blacking out the entire town.
Ron: "Land, ho!"
Drakken: "No kidding."
In Rudolph the Red Nosed Reindeer, when Hermey the elf and company are on the iceberg and they come to land, Yukon (the miner) yells "Land, ho!" and Hermey responds "No kidding".
Drakken: "All I want is what's coming to me. All I want is my fair share!"
When Drakken pouts and says this, it's a reference to A Charlie Brown Christmas. Charlie Brown's little sister Sally utters roughly the same line when Charlie Brown comments on her letter to Santa requesting "10's and 20's".
Rudolph the Red-Nosed Reindeer:
Snowman Hank is very similar to the narrator snowman in the claymation Rudolph the Red-Nosed Reindeer.
Drakken's Sign: Bah Humbug:
Drakken's sign quotes Ebenezer Scrooge's catch-phrase from the Dicken's classic "A Christmas Carol".
Drakken: They'll be drinking eggnog, singing carols, eating roast beast, playing with hob nobbles....
Dr. Drakken's rant includes some verses from the Dr. Seuss classic How the Grinch Stole Christmas
Ron: Information, can you get me the number for 911, immediately please!
This is a dig at the famous Simpsons quote where Homer yells "What's the number for 911?" Also, 911 is a common emergency number in the USA.
