- Adaptation Displacement: There's quite a lot of people who don't realize that Dr. Elmo has a lot of Christmas songs besides the one which spawned this special. Many of them, such as "Grandma's Killer Fruitcake," appear in the special, but some viewers mistakenly assume they are original to it.
- Americans Hate Tingle: This special, much like the song which inspired it, is unpopular in Canada, to the point where it had only one airing on a Canadian channelnote .
- Big-Lipped Alligator Moment: Every musical sequence, although one has the excuse of Grandpa being a Cloudcuckoolander. The only song that truly has much connection to the story and is actually referred to is the title song.
- The ET reference that lasts for all of ten seconds when Jake meets the elf in his room.
- Ear Worm: The Villain Song is the bad kind.
- Ensemble Dark Horse: Cousin Mel.
- Evil is Sexy: Cousin Mel.
- Her lawyer, I.M Slime isn't bad looking either.
- Heartwarming Moments: It may have been random, but there's something oddly endearing about Grandpa's song, wherein his supposedly dead wife is being comforted by deceased celebrities in Heaven.
Grandpa: Grandma's spending Christmas with the super stars
Since that reindeer ran her down that fateful night
Grandma's hanging out with all those late great stars
For the heavenliest Christmas of her life!
- Idiot Plot: The excuse that Santa gives as to why he didn't bring Grandma back is because since she has amnesia they don't know who she is. That is a really crappy excuse seeing as how after they made sure she was okay, they could've just come back to the same spot she was run over, and asked the people nearby as to who this woman is. Instead he just leaves her at the North Pole for an entire year, and apparently during that whole time doesn't check missing persons reports to try to figure out who she is. Kind of makes you wonder if the court was right to let him go.
- Let's not forget the fact that he's Santa. He knows the name, location, and goodness/badness of everyone in the world. He should have known who Grandma was immediately upon seeing her. They could have avoided this massive Plot Hole if they had made it so that Santa's knowledge is limited only to children, but no, when he meets Austin Bux face-to-face, he names him and tells him of a present he wanted as a kid to prove that he's really Santa. This gives him absolutely no reason to not know who Grandma was.
- Les Yay: It's almost impossible not to think Cousin Mel and I.M. Slime are a couple even if Mel expresses attraction to Austin Bucks.
- Memetic Mutation: No pantalones.
- Moral Event Horizon: The fact that Cousin Mel was perfectly willing to poison innocent strangers just to get Grandma to sell the store put her over the line.
- Most Annoying Sound: Grandma's voice is incredibly high-pitched and nasal. Plus the song, love it or hate it, is one hell of an Ear Worm.
- Nightmare Fuel: As undoubtedly cheesy as this movie is, it's still kind of unsettling to imagine seeing a beloved grandparent be struck down, and then disappear for over a year with no one willing to believe you when you tell them what happened.
- Older Than They Think: In the music video for the song, Grandma also went missing after she disappeared outside the family home, and the scene cuts to the cops obtaining hoof marks and showing them to Santa (who's in handcuffs), implying her death. This, too, turns out to be a Disney Death, as toward the end of the video, Grandma slides down the chimney to their surprise, alive and well, but also fazed, and delivers her line in the end of the final verse: "They should never give a license / To a man who drives his sleigh and plays with elves."
- So Bad, It's Good: The voice acting sounds, at times, incredibly stilted and several characters were given actors that aren't well-suited for the part; the jokes and puns are almost always groan-inducing; and the animation isn't anywhere near as fluid as it could have been. Even so, it's really hard to dislike this special, Adored by the Network notwithstanding, mostly because of issues with the production.
- What An Idiot: After spending so much time with an Amoral Attorney, you'd think Cousin Mel would know better than to just suddenly confess literally EVERYTHING.
- The Woobie: Jake and Grandma.
- Jake, because his validation in believing in Santa Claus is immediately followed by Santa and his reindeer running down his grandmother. His family stops him from going out to help Grandma, and when they do let him out, she's gone. This is followed by a year of no one except his senile grandfather believing him about what actually happened, the police are no help, and it's ultimately down to Jake to carry on the search by himself because no one will help him.
- Grandma, of course, for not only getting run over by Santa, but spending the following year with a horrible case of amnesia to the degree that, not only can she not remember anything before the accident, she can't even form memories that last for long.
