- Anvilicious: "Miku Hits R2 with a Chair" and "Hate" end with And Knowing Is Half the Battle sequences laying out their morals (suicide prevention and toleration of immigrants, respectively) unsubtly. The latter in particular caused a Broken Base because some viewers found it to be extremely effective, however.
- Broken Base: "Hate", the first season finale, split viewers because of its explicitly political message about immigration and discrimination (including shots at Donald Trump's controversial policies regarding the former). Was it an anvilicious moral that was jarring in a normally goofy series, or a case of Some Anvils Need to Be Dropped that was pulled off well? (In any case, the reception led to the creator made it private just a day after it was uploaded.)
- Crosses the Line Twice: Quite a bit, especially Gumi getting thrown into a giant blender.
- Jerkass Woobie: Miku. She's selfish, impulsive, and stupid, but she's hated by everyone who isn't R2 and always suffers for her bad decisions.
- Nightmare Fuel: SeeU is a man-eating monster who knows things she should have no way of learning. And she survived her apparent death.
- Some Anvils Need to Be Dropped: As unsubtle as the series' more serious episodes can get about their messages, no one can deny that their points don't ring true.
- What Do You Mean, It Wasn't Made on Drugs?: Entirely averted. The creator stated that he got high on mushrooms prior to creating the original "Episode 29" short, and the series' standard disclaimer continues to hold that they involve drug use. (The lone exception being "Miku Hits R2 with a Chair", which was apparently made with a desire to convey a message about suicide.)
- The Woobie: Gumi and Turret, both genuinely innocent sweethearts who still suffer as much as anyone else does on this show.
