Star must show a magical inspector named Baby what she has learned about magic.
Tropes:
- Awesome, but Impractical: Star has never really bothered with learning how to properly use her magic, almost always going for brute-force types of spells. This episode shows that brute force isn't always a good thing, especially when trying to do something basic.
- Bait-and-Switch Character Intro: Baby is first introduced as a cloud of ominous dark smoke, fitting her role as The Dreaded; but once the smoke clears, she resembles nothing more than a Cute Kitten with fairy wings.
- Bait-and-Switch Comment: Baby tells Queen Moon "Star is nowhere near your skill level at her age... she's far beyond it."
- Batter Up!: After getting scared off by Baby when offering a plate of sandwiches, Marco enters the room a second time, wielding a bat.
- Beware the Cute Ones: Baby may look cute, but she's quite stern, and although we don't get to see much of her angry side, the brief glimpse she gives Marco is terrifying.
- Big Eater: Baby eats an entire snack table that Marco spent all day preparing in an instant, and then asks for more. She also takes King River's food right off his hands.
- Brick Joke: While cleaning her room, Star hides much of her stuff in a dimensional portal. Later, when she tries to use a portal to pass Baby an apple, all her stuff falls out of it. Some of her other junk gets stuffed into a chest that Star gives wings and makes fly away. After Baby leaves, Marco and Star are looking out her balcony and see the chest has joined a flock of geese.
- Brutal Honesty: Star asks Baby how she did on her evaluation, and after going over her papers Baby bluntly informs Star: "You failed! Goodbye."
- Continuity Nod: The unexplained kicking-Star-legs thing from "St. Olga's Reform School for Wayward Princesses" is seen crammed into a trunk as Star cleans up.
- The Dreaded: Baby is this not only to Star, but also to King River, who dislikes that she keeps taking all his food.
- Foil: Baby to Glossaryck. She is more stern and strict when assessing Star's magic and skills, but more honest and direct in her training.
- Freak Out: Star is desperately trying to clean her room after she hears that Baby is coming.
- Gentle Touch vs. Firm Hand: As mentioned elsewhere on this page, Baby employs the Firm Hand and contrast to Glossaryck's Gentle Touch.
- Get Out!: Baby snaps this at Marco (in a deep, ominous voice) when he interrupts her dressing-down of Star.
- In the Blood: Star has more in common with Eclipsa, both in magic's skills and power as in personality traits.
- Jerkass Has a Point: Baby does not sugarcoat how badly Star has failed the test, but every putdown and condemnation she has is perfectly true, right down to the point where Star pleads that if she fails, she has to go home."That's not my problem."
- Match Cut: The final shot is a close-up of Star in the family portrait, which fades into the portrait of Queen Eclipsa.
- Mundane Made Awesome: Baby tests Star by having her pass her an apple using only her magic. After many failed tries, Star finally has a tree grow from the apple and produce an apple of its own, right in front of Baby just as she's about to leave. This impresses Baby, as it shows powers far beyond that of any previous Queen of Mewni — except for Eclipsa.
- Nightmare Face: Baby gives Marco one as she tells him to "Get Out!!"
- "The Reason You Suck" Speech: Baby's initial assessment of Star, pointing out her closet of secrets, her carelessness with the wand and Spell Book, and her lack of basic magic skills.
- Slowly Slipping Into Evil: Baby has reason to believe Star's irresponsibility will turn into outright villainy, and her power is rather concerning.
- Technician Versus Performer: Star doesn't know basic magic but managed to pass the test with a spell she instinctively cast.
- Unskilled, but Strong: Baby concludes that while Star lacks finesse and a grasp of simpler fundamental magic, her magical potential is incredible.
- Villainous Legacy: In a sense. Baby thinks that Star's magic power and skill far surpasses that of Queen Butterfly's and that she hasn't seen anything like this since Eclipsa the Queen of Darkness.
- Wham Line: "Star is nowhere near your skill level at her age... she's far beyond it. In fact, I haven't seen anything like this... since Queen Eclipsa."
- Yin-Yang Bomb: As Star gets more nervous her stable pink magic becomes unstable and green, mutating the apple. When she casts one last spell, it's a mix of both pink and green magic. The green magic neatly splits the apple, then the pink magic sprouts an apple tree from a seed which grows a new apple for Baby.
