- Animation Bump: When Harman and Ising were brought back in 1939 to give the MGM Cartoon Studio the kick in the pants it needed, they had used the time in their absense to considerably refine their animation skills to the point of full-blown Disney quality, resulting in The Twelve Principles of Animation being in full effect in these shorts. It helped that Harman And Ising had in fact worked on one outsourced Silly Symphonies short, "Water Babies", during that time.
- Anti-Villain: The eponymous wolf of "The Hungry Wolf"; he does want to eat the little kid rabbit who unwittingly comes to his house, but it's clear he was literally starving to death in the first place, and eventually the wolf gets guilty enough about his desires to where he forcibly throws the rabbit out to keep himself from eating him—which fails and he tries to go after him, only for the snowstorm to get the better of him. Ironically, the rabbit and his family take him in during the storm, and the wolf is very grateful for this.
- Artistic License – Astronomy: "The Milky Way", which has literal milk. Also "Little Buck Cheeser" with it's cheese-moon.
- Ascended Extra: The donkey from "Little Gravel Voice" would later make a couple appearances in the Barney Bear cartoon series, and even became a recurring character in the Barney Bear comics, even receiving the name of Benny Burro.
- Bittersweet Ending: "The Little Mole"; the kid gets his new glasses broken and comes close to drowning, but he ends up reunited with his mother by the end, and he can once again see his "Dream Castle" (a pile of junk which he imagines is the former due to his very poor eyesight).
- Big, Friendly Dog: The family of Saint Bernard rescue dogs in "Little Cesario"; ironically inverted with Cesario himself in terms of size, but he's still just as friendly.
- The Cameo: Spike the Bulldog makes a brief cameo in "War Dogs".
- Carnivore Confusion: "The Hungry Wolf", in which a starved wolf just can't bring himself to eat the cute little bunny who shows up at his doorstep (though he almost does).
- Cigar Chomper: The Spider in "Mrs. Ladybug".
- Crouching Moron, Hidden Badass: "Little Cesario", a Saint Bernard pup who initially seems rather unhelpful, but became instrumental in saving the older Saint Bernard, Alexander, from a heavy snowstorm and avalanche.
- Crying Wolf: "The Boy and the Wolf".
- Cute but Cacophonic: The donkey from "Little Gravel Voice"; his bray is not only extremely obnoxious, but literally harmful, as the wolf it encounters later finds out the hard way.
- Cute Kitten: The trio of kittens in "The Milky Way".
- Denser and Wackier: "The Lonesome Stranger", a parody of western cartoons, is noticably more gag-oriented and wild in it's animation than most of these other shorts.
- Digital Destruction: The restored version of "Tom Turk" has atrocious, blatant DVNR damage in many parts of the short.
- Dog Face: Officer Pooch, from the eponymous short.
- Family-Unfriendly Death: The fate of the Spider in "Mrs. Ladybug"; after unwittingly swallowing his cigar to hide it from the nearby kid, it burns him from the inside and he drinks something nearby to put it out—only to find out it was a jug of gasoline! Seconds later, he violently explodes and is sent to Kingdom Come.
- Furry Confusion: "Officer Pooch" has both a Dog Face and a non-anthropomorphic dog.
- Get Out: The Wolf from "The Hungry Wolf" angrily says this several times to the kid rabbit before forcing him out of his house, but it's to keep himself from trying to give in to eating the kid.
- Jerkass Façade: The Wolf from "The Hungry Wolf" angrily throws the kid rabbit out of his house, in an attempt to keep himself from trying to eat him.
- I Just Want to Have Friends: The premise of "Little Gravel Voice"; the protagonist is a cute, friendly little donkey who suffers from having a bray so dreadfully obnoxious that it scares away all the other animals. Ironically, his bray ends up harming and scaring away a hungry wolf, which earns him the friendship of the other animals—once they tie up his snout with his ears, of course.
- Limited Animation: "The Dot and the Line".
- Musical Episode: Several of them are, like their predecessor series Happy Harmonies.
- No Celebrities Were Harmed: "Art Gallery" features several caricatures of famous movie stars of the day. "Gallopin' Gals" also features caricatures of female celebrities of the time period.
- Public Domain Soundtrack: "Blue Danube", although there are custom lyrics made for it in the short.
- Rotoscoping: Used in Blue Danube, Goldilocks and Peace on Earth.
- Sentient Vehicle: At one point in "Innertube Antics", when the eponymous tube rips the donkey's old Jalopy out of its frame, it crashes through his house's wall—and is found relaxing on the bed, smiling.
- Shaggy Dog Story: "Art Gallery". Once it looks like Nero has succeeded in burning down the art museum, everything abruptly returns back to normal.
- Spiritual Successor: Many of them are essentially Happy Harmonies with more lavish animation, hence why a few of these shorts featured previous stars of the Harmonies shorts.
- Smelly Skunk: Dr. Primrose Skunk from "The Little Mole"; his first appearance has several flowers go limp as he walks by.
- Transflormation: "The Tree Surgeon" revolves around an unintentional one.
- The Twelve Principles of Animation: In full-blown effect. The shorts are very solidly drawn, and the films are loaded with more squash and stretch and secondary actions than you can imagine.
- Villainous Breakdown: The wolf from "The Hungry Wolf" is driven to this when he kicks the kid rabbit out of his house to keep himself from eating him, and then succumbs to his hunger shortly after. Thankfully, the snowstorm outside gets the better of him, and the rabbit and his family save him and welcome him into their house (and the wolf is grateful for this).
- The Voiceless: Pantomime was frequently used in the shorts, with some characters having no dialogue whatsoever. "Officer Pooch" is a notable example of this.
- Wartime Cartoon: "War Dogs" and "The Stork's Holiday". "Innertube Antics" is not an explicitly war-themed cartoon, although the rubber scrap drive of the short is an obvious nod to the strict rationing of rubber during the war years.
- Wholesome Crossdresser: The Crow in "The Bookworm" tries to lure out the worm by attempting a "Little Bo Peep" sham. The worm isn't fooled.
