Voiced by: Alex DodukThe main protagonist of the special, a boy around the age of about 10-12 and of course a modified version of David from the sequel film of All Dogs Go to Heaven.
- Adorably Precocious Child
- Agent Mulder: He believes in Santa Claus from the start, even before Grandma got run over by a reindeer.
- Beware the Nice Ones: He most likely gets this from Grandma. As nice and as helpful as Jake is, Cousin Mel learns the hard way that messing with Grandma was a surefire way to get on his bad side when he gets her thrown in prison. He's also clearly enjoying the hell out of watching Mel squirm when all the evidence against her leaves her with no more ways out, and forces Mel to confess to everything she did.
- Brainy Brunette: He's pretty smart for his age.
- Cassandra Truth: Nobody believes his claim that Grandma got run over by a reindeer early in the movie, even when he's wide eyed and screaming it. They don't particularly believe him either when he says that Santa is real, even though there's clearly evidence that suggests that he is indeed real.
- Deadpan Snarker:I.M. Slime: Mel's Attorney: I.M. Slime.Jake: Well, you said it, not me.
- Determinator: Absolutely refused to stop looking for Grandma even after a year had gone by.
- Grandma's Boy: He seems to be closer to Grandma than anyone else in the family, except for Grandpa.
- Nice Guy: He's easily the nicest character in the movie, being more than willing to help his grandmother when nobody else will and even helping out Santa Claus. As demonstrated above, however, that doesn't exactly mean that it's a good idea to provoke him.
- Only Sane Man: In a way, since, he's the only one who actually saw what happened to Grandma and had still been looking for her for over a year, long after everyone, including his own family, had given up.
- Wise Beyond Their Years: As mentioned above, he's pretty smart.
- You Have to Believe Me: In regards to what happened to Grandma. The fact that slightly senile Grandpa is the only other witness didn't help his case.
Voiced by: Susan BluJake's Grandma, who owns a small department store in the city, the only piece of property not owned by super company Austin Bucks.
- Beehive Hairdo: Largely to fit the design of the grandma from the song
- Beware the Nice Ones: Almost lets loose on Cousin Mel after she whines about Grandma not selling the shop, before saying "but Grandmas shouldn't talk that way." She also makes it clear to the family that if she'd gotten more help besides Jake with the decorating (like she asked), she wouldn't have been leaving so late that night. The look on her face and her tone of voice makes it clear she's pissed off.
- Cool Old Lady
- Easy Amnesia: After the reindeer incident. It was so bad she was incapable of retaining any permanent memories.
- Everyone Calls Her Grandma
- Foot Focus: We get a shot of her feet as she's preparing to leave the house on that fateful night.
- Friend to All Children: She dresses up as an elf and reads to kids in her store during the holidays.
- Good Is Not Dumb: Despite what Cousin Mel thinks, she's actually an intelligent businesswoman, since her generosity keeps her costumers loyal, and doesn't trust Mel one bit with her business.
- Grandma, What Massive Hotness You Have: She actually looks quite cute for her age.
- Granny Classic: Definitely has the look.
- Happily Married: To Grandpa.
- The Heart: Without her, the store was never the same.
- Lethal Chef: Averted. Despite the song "Grandma's Killer Fruitcake" her baked goods and pastries are insanely popular and delicious, especially her fruitcake. The one batch that turned out bad was the one Cousin Mel intentionally poisoned to make people sick.
- Made of Iron: Amnesia not withstanding, the woman managed to survive being trampled by eight reindeer and a sleigh. Twice.
- Plot Allergy: Her supposed allergy to eggs. One of the reasons she'd been heading out was because she left her medication at the store.
- The Smart Guy: Is easily the smartest person in her family besides Jake. She was the primary manager of the store and the reason it was going for so long. This gets highlighted during her disappearance when, nine months later, Jake's parents are actually trying to sell the last fruitcake she made. A year old fruitcake that was on the ground, in the cold, partially chewed by their dog, and used as police evidence.
- Spared by the Adaptation: She is pretty obviously killed in the song.
Grandpa SpankenheimerGrandma's husband.
- Cloudcuckoolander: Implied he's turning senile.
- The Cloudcuckoolander Was Right: He's the only one apart from Jake (and Grandma) to see the reindeer run over Grandma.
- Disney Acid Sequence: His song pretty much comes out of nowhere.
- Everyone Calls Him Grandpa
- Happily Married: To Grandma. Yet he did nothing to actually go and help her after seeing her get run down by Santa's sleigh.
- Nice Job Breaking It, Hero: He walks right into Cousin Mel's trap by signing her contract. He thought he was helping.
- He also knocked down the inflatable Christmas tree in the beginning.
- OOC Is Serious Business: When reading the letter Santa wrote explaining what happened, he gets angry for the first time ever. The look on Cousin Mel's face when she realizes she got Grandpa mad makes it clear she knows she's beyond screwed.
Voiced by: Michele LeeThe main antagonist of the special and Jake's cousin.
- Abhorrent Admirer: To Austin Bucks.
- Adaptational Villainy: In the song, Cousin Mel is only given a brief mention as playing cards with Grandpa after Grandma's death, and doesn't seem particularly malicious. Here, she's elevated to the position of main antagonist.
- And There Was Much Rejoicing: One way of looking at her Disney Acid Sequence song with I.M. Slime is that the two of them were completely ecstatic when they realized just how much money they could get for suing Santa.
- Ascended Extra: In the song, she's barely mentioned.
- Big Bad: Her selfishness and greed are what drives the conflict of the movie.
- Beauty Mark
- Brilliant, but Lazy: She can be exceedingly ruthless and manipulative when she puts her mind to something, but most of the time she just whines about Grandma's business practices.
- Deep South: If her accent gives anything to go by.
- Double Entendre:Cousin Mel: Now Austin, darling, why don't we go somewhere romantic and consummate this deal?
- Evil Cannot Comprehend Good: Hates "the goody goody feelings of Christmas".
- Evil & Fiery Redhead
- Excessive Evil Eye Shadow: Subverted. Not necessarily excessive, just enough to make evil sexy.
- Exposed to the Elements: The only character not dressed appropriately for winter.
- Femme Fatale: She tries to schmooze both Grandpa and Austin Bucks with her good looks. She manages to wrap Grandpa around her finger (if only because he's senile to begin with and didn't know what she was really up to), but she's not so lucky with Austin, given that he chooses to give Jake a chance to find his grandma instead of letting Mel have her way right then and there.
- Femme Fatalons: Although she never actually puts them to any use.
- Gender-Blender Name: Mel is typically a male name.
- Gold Digger: She is explicitly described as one by Grandma.
- Greed: All she cares about is getting rich any way she can.
- The Grinch: Pretty much stated during her confession she doesn't like the spirit of Christmas.
- Hyper Awareness: Subverted. The fact that she noticed a few key things, such as the letter Santa left behind and Santa actually arriving with Jake and Grandma, are what allowed her to put her plans in motion.
- Idiot Ball: Why she held onto that letter stating what really happened is anyone's guess, but the fact that she did was pretty much Mel shooting herself in the foot.
- Likewise leaving the spice in her purse. Doofus manages to pick up it's scent and leads Jake to where she keeping Grandma hidden.
- Impossible Hourglass Figure: She's got quite a curvy figure, which adds well to the fanservice.
- Irony: She goes to all the trouble to try to get rich. Then after she's thwarted and sent to jail, her family does get rich when Austin offers to turn the Spankenheimer store into a franchise.
- It's All About Me: "Hey, I deserve to be rich."
- Jerkass: Undoubtedly the biggest offender in the movie; even Daphne's nowhere near as unpleasant as she is.
- Kick the Dog: She made her grandma suffer Laser-Guided Amnesia and framed Santa for her disappearance.
- Lack of Empathy: It's pretty clear that she doesn't care about poisoning people to get rich. Neither does she care about nearly ruining Christmas by almost landing Santa in jail.
- Laser-Guided Karma: She goes to jail for obstructing justice by hiding Santa's letter.
- Lazy Bum: Wants money, does everything beyond actually working to try and get it and pretty much sponges off Jake's family. The only time she's ever shown working is when she thinks someone is shoplifting.
- Male Gaze: Pretty much any scene, particularly during her villain song, where she is dancing with a Fur Bikini top, and her Cleavage Window has widened. See it here◊.
- Manipulative Bitch: Is a contender for third smarter person in the movie behind Grandma and Jake. Up until the ending she managed to effortlessly turn around every hitch she encountered to her advantage.
- Ms. Fanservice: Just take a look at the picture above and the associated quote.
- Nice Shoes
- Parent Service
- Redhead In Green: She has red hair and wear a green shirt.
- The Relative Nobody Likes: It's clear she's not the most beloved member of the family so why she's living with them at all is anybody's guess. It's not even clear as to whose cousin she is.
- Troperiffic: Especially when compared to the other characters. She displays many of the typical villain and Fanservice tropes.
- Unexplained Accent: She speaks with a slight southern accent while the rest of her family doesn't. Might make sense since she's just their cousin and probably grew up elsewhere.
- Unwitting Instigator of Doom. While her plan was to poison people by spiking Grandma's fruitcake, she didn't mean for it to attract the reindeer that ran her down. It's later averted when she and her attorney kidnap Grandma, just so they could sue Santa over her disappearance.
- Victoria's Secret Compartment: Where she puts Austin Bucks' phone number and Santa's letter.
- Villainous Breakdown: Once its pretty obvious that there's too much evidence stacked against her for her plan to work anymore.
- Villain Song: "Grandpa's Gonna Sue the Pants Off Of Santa", which she shares with I.M. Slime.
- Wingding Eyes: She experiences the dollar sign variant.
- Would Hurt a Child: Not directly, but she had no qualms with anyone getting sick from her poisoned fruitcake, which could've been anyone, including kids. She's also not very fond of Jake.
- Big Good
- Cool Old Guy
- Happily Married: We see Mrs. Claus at points in the film who's naturally worried for him after he's convicted of hit and run and kidnapping. And he holds her warmingly as they're about to head back to the North Pole.
- Reasonable Authority Figure: A main rule of thumb is that humans aren't allowed to the North Pole without permission. So he let's Quincy slide when he brings Jake there to find his grandmother.
- Santa Claus: This is the man himself we're talking about; it's a given.
- Amplified Animal Aptitude
- The Nose Knows: Being a dog and all. Manages to help Jake track where Mel had hidden Grandma during Santa's trial.
- Unfortunate Names: Who Names Their Dog Doofus?
Austin BucksA rich business man who owns every store in the city, save for Grandma's.
- Corrupt Corporate Executive: Averted, despite initially being set up as such. He wants to buy Grandma's shop but he's not willing to go to any illegal lengths to acquire it, and gives Jake a fair chance to find Grandma before he signs the deal with Cousin Mel. Likewise after everything said and done, he offers to turn Grandma's shop into a franchise.
- Hidden Depths: When he was six, he wanted a Lieutenant Neutron Action Figure.Austin: Lieutenant Neutron? He was the best!
- He also had a chance to go somewhere romantic and consummate a deal with Cousin Mel, which pretty much any other guy would've taken, but he chose to give Jake a little extra time to find Grandma.
- Honest Corporate Executive: As mentioned in the above two entries, despite being set up as this initially, he's actually a pretty decent guy who's more that willing to give Jake a fair shot at finding his grandmother before signing off on Cousin Mel's deal.
- Meaningful Name: The guy's last name is "Bucks" and he owns a massive corporation. You can piece the evidence together.
I.M. SlimeCousin Mel's attorney who helps her frame Santa Claus for Grandma's second disappearance.
- Amoral Attorney: Does everything she can to ensure her client gets her fraudulent cash payoff, including aiding in a kidnapping scheme.
- The Dragon: To Cousin Mel.
- Facepalm: After a now lucid Grandma shows up in court and Cousin Mel shouts "That woman is a fraud! Grandma doesn't know who she is!"
- Doubles as an Oh Crap! as well as she knows they're pretty much screwed.
- Karma Houdini: Disappears at the end of the film with no sort of comeuppance for her hand in almost destroying Christmas.
- Meaningful Name: She's a lawyer. Get it?
- Names to Run Away from Really Fast: Jake's reaction to meeting her for the first time:Jake: Who are you?I.M. Slime: Cousin Mel's attorney. I.M. Slime.Jake: You said it, not me.
QuincySanta's head elf.
- Hyper-Competent Sidekick: Like Jake, he likewise was trying to find out who Grandma belonged to and eventually does when he gets Jake's letter to Santa to bring his Grandma home. He also helps out Jake recover Grandma from the cabin Mel was keeping her hidden away in.
- Worth It: Give the guy credit, he knew there was a risk in bringing Jake to the North Pole without Santa's permission. But did it anyway which luckily for him allowed him to keep his job.
Spankenheimer FamilyJake's mother and father (the father of which is the son of Grandma and Grandpa) and his elder sister Daphne (not that Daphne.) note .
- Adults Are Useless: They don't really prove to be much help both before the incident (making excuses to get out of helping Grandma with charity work and decorations) and after (all but giving up the search for Grandma. Hell Daphne at one point tells Jake to give up). But hey it's a kids movie. Par for the course.
- Jerkass: Daphne, Jake's sister. She spends most of the movie ranging from being a bratty sister to being a complete asshole to Jake. She softens at the end when Jake proves he was right about Grandma and Santa.
- So Proud of You: Stated to Jake after he both finds their Grandma and saves Christmas.
