Rhombulus is convinced that Star is the source of a universe-wide magical glitch and brings her before the Chancellor of the Magical High Commission.
Tropes:
- All Crimes Are Equal: Rhombulus will crystallize people for blowing up planets, creating black holes, and delivering pizzas to the wrong address, or sometimes for no reason other than his gut instinct telling him.
- Armor-Piercing Question: Rhombulus' job is to imprison evil creatures in crystal. Star asks why, among the people he's crystallized that night, the list includes his adored boss Lekmet and his own two hands, which makes him realize his error.
- Black Comedy: Rhombulus and Star having a tea party using the crystal Marco is frozen inside as a table.
- Body in a Breadbox: Rhombulus stuffs Marco into his fridge.
- Bottle Episode: Most of the episode takes place in Rhombulus' lair, and the second half is mostly just him and Star talking.
- Call-Back: The magic glitch mentioned back in "Page Turner" is brought up. The same episode showed Rhombulus being put on time out, hence Star calling him "Time Out Guy".
- Crystal Landscape: Rhombulus' dimension is a crystal clear case of this.
- Crystal Prison: Rhombulus traps (supposedly) evil creatures in crystal. Unfortunately, the magic fritz is causing them to weaken...
- A Day in the Limelight: We learn a lot about Rhombulus in this episode.
- Didn't Think This Through: Rhombulus captures Star, daughter of one of the Magic High Council members and the crown princess of Mewni, suspecting her of being the cause of the magic glitch on a gut feeling without any evidence. His attempts at damage control dig him even deeper into a hole.
- Evil Twin: Two of Rhombulus' prisoners are a pair of small furry monsters in which one of them was definitely a criminal, but because Rhombulus couldn't tell them apart, he just crystallized both of them with no evidence that the other twin was evil at all.
- Foreshadowing: Rhombulus claims his diamond-like crystal prisons have weakened to a hardness closer to rock candy due to the glitch. His lair is decorated with a Rogues Gallery including someone who blew up a planet, someone in the middle of creating a black hole, and Queen Eclipsa.
- Heel Realization: Star convinces Rhombulus that his habit of crystallizing people at the drop of a hat isn't a good thing.
- He Knows Too Much: Rhombulus crystallizes Marco, Lekmet, and his hands over the course of the episode, solely because they've witnessed his screwups.
- Heterosexual Life-Partners: Rhombulus lives with and cares for Lekmet due to the latter's advanced age. Later subverted through
Word of Gay. - Intelligible Unintelligible: It seems Rhombulus is the only person who can understand what Lekmet says.
- Knight Templar: Rhombulus will crystallize and imprison anyone he even thinks is evil.
- Losing a Shoe in the Struggle: Star manages to slip out of her Crystal Prison once Rhombulus melts the top of it; however she has to leave both socks inside in order to free her feet.
- Made of Diamond: Rhombulus claims his crystals used to be as hard as diamond, until the glitch caused their hardness to weaken.
- Meaningful Background Event: One of the figures in Rhombulus's collection of imprisoned bad guys is Queen Eclipsa.
- Multiple Head Case: Rhombulus's snake hands have a mind of their own, and try to convince him that abducting Star isn't a good idea.
- Pajama-Clad Hero: Star is dragged off by Rhombulus to his lair in the middle of the night while in her nightgown.
- Sealed Evil in a Can: Rhombulus's crystals are the can for multiple evils, but they're weakening.
- The Tooth Hurts: Star hurts her teeth when she tries to eat a crystallized donut.
- Wham Shot: One of Rhombulus's crystalized prisoners is Queen Eclipsa.
