Christmas Episode: Natch, even though this takes place during the summer.
Fisher Kingdom: After a prolonged stay in Holiday Village, Ben and Gwen start turning into elves, as evidenced when their eyes become beady, their cheeks turn rosy, and their ears grow pointy.
Fish out of Temporal Water: Inverted. It's our modern heroes who are out of place in Mr. Jingles' preserved 1932 world. As exemplified, there's an exchange between Ben and Elsgood where the former is astounded the latter only knows outdated words like "skedaddle" and "spiffy". In turn, Elsgood is baffled when Ben uses the term "dude".
Killed Off for Real: Mr. Jingles disappears (having retroactively lived out his life) when his Christmas magic wears off, making him the only human character in the show who dies. Unlike other instances, he never returns in the sequels.
Meaningful Echo: When Mr. Jingles fusses over how Ben's meddling has ruined his plans to give the world the perfect Christmas, it's Max who advises that Christmas is less about presents and more about the family and generosity. Later, when everything has returned to normal, our heroes discover a statue with Mr. Jingles quoting Max verbatim. Sweetly, this indicates how he relented his extremist approach to Christmas and took Max's advice to heart.
Mr. Alt Disney: Mr. Jingles gets a statue depicting him holding hands with an elf, much like Walt himself has a statue with the same pose where he's holding Mickey's hand.
Narnia Time: The flow of time within Holiday Village is so dilated from the outside, Elsgood thinks it's only been a few days when he's been in there since 1932.
Offscreen Villain Dark Matter: Somehow, a man in 1932 gained access to highly advanced, enchanted technology to lock a pocket of dilated time around a small town and transform the children present into elves.
Shout-Out: At the end, a grown-up Elsgood is seen with three kids that look like Konohamaru and his friends. One even has a t-shirt depicting a swirled lollipop, emulating the Hidden Leaf Village's insignia, to drive the reference home.
Something Only They Would Say: When Ben and Gwen last meet Elsgood, he's initially unrecognizable as an old man with grandchildren of his own. But when his grandchildren ask to further explore Holiday Village, he affectionately uses the 1930s jargon "skedaddle". Ben and Gwen instantly recognize him then, and he confirms his identity with a wink.
Timeshifted Actor: Kim Mai Guest does Elsgood as a child while Dee Bradley Baker does the elderly version at the end.
Well-Intentioned Extremist: Mr. Jingles wants the world to have a perfect Christmas. To this end he kidnaps, transforms, brainwashes and enslaves people to act as elves and Santa to give the world his idea of a perfect Christmas. He's been working since 1932 doing this, keeping children from their families on Christmas all this time.
