Big-Lipped Alligator Moment: The Talent Suckers appearing in a time machine and then disappearing in "Puffy B.C." It comes out of nowhere and has no bearing whatsoever on the episode's plot.
Covered Up: The soundtrack features a cover of "Joining A Fan Club", originally by Puffy songwriter/producer Andy Sturmer's early-1990s band Jellyfish.
Thanks to the theme song played by the same group, it naturally has one with Teen Titans (2003).
Due to following the "goth girl and pastel girl" dynamic and having a similarly trippy tone, you'll find a lot of Panty & Stocking with Garterbelt fans who enjoy this series.
An Americanized show about two Japanese pop stars has a very popular Hispanic dub.
Predictably, the show was more popular in Japan than America, to the point that Japan got the entire series on DVD while America didn't.
Jerkass Woobie: Julie may be a Jerkass who tried to kill Ami and Yumi, but it's hard not to sympathize with her for wanting to be popular like them. The ending to the episode makes her even more sympathetic, with the visual of her being left in the rain during her Villainous Breakdown and unable to do anything more than vow revenge looking especially pitiful.
"Bad Manager": Slick Shady, the "biggest weasel in rock", is a manager who's also an expert rock-paper-scissors player. Coercing the reluctant Kaz into betting his prize money in a game of rock-paper-scissors, Shady easily wins, and gets him to bet Ami and Yumi, whom he also wins. With the duo now his, Shady lavishes them in an ultra-luxurious lifestyle, all while Kaz degrades into a washed up flea circus manager. After Ami and Yumi challenge Shady to a game of rock-paper-scissors for their release, he ups the ante by forcing Kaz to leave the music business should they lose. A man of his word, Shady allows Ami and Yumi to return to Kaz after they beat him, while also leaving his mark as the best manager the duo have ever had.
"Phantom of Rock": The titular Phantom of Rock, Johnny Ghost, is a legendary rocker who can get the best out of any band. Working with Kaz to get Ami and Yumi out of their creative stagnation, the Phantom fakes kidnapping Kaz and has the duo go through his deadly haunted castle. At the end of the trail, the Phantom reveals that he had sampled Ami and Yumi's screams and grunts to be used in an enjoyable single, ending the episode willing to collaborate with the Puffy gang again after having so much fun messing with them.
"Legend of Mei Pie": The eponymous Master Mei Pie is the greatest guitar maker in the world, and the one Yumi goes to for a new guitar. Mei Pie gives the rocker a list of items that require her to travel around the globe, uncaring that Yumi goes through pain to retrieve them. Once all the items are brought to him, Mei Pie, rather than giving Yumi a new guitar, instead returns her old one to her, stating that the entire thing had been a test to see how much effort she would put into accomplishing her goals, with Yumi playing far better now than she was before thanks to his methods.
Memetic Badass: Ninja Ami and Ninja Yumi, to the point where their outfits are featured in the video games and in the Ninja Rockstar computer games.
Spiritual Successor: This show busts it's seams to capture the goofiness of celebrity cartoons that Sam Register is a fan of. Even down to having the live action Ami and Yumi bookend the segments akin to the format of pre-The Flintstones era of cartoons with the format of three shorts framed by a live action segment. Also following in the footsteps of Chuck Norris and Mr. T who did live action segments for their own cartoons.
Superlative Dubbing: The excellent Spanish dub was the reason of its popularity in Latin America, with Karla Falcon as a snarky Yumi and Leyla Rangel as a overly cute Ami and the good chemistry and comedic timing they had.
Sweetness Aversion: The color scheme and overall "cuteness" of the series is likely to turn away a lot of viewers.
Unintentionally Sympathetic: Kaz, is usually mistreated by Ami and Yumi's cats, and occasionally when he manages to blow their cover in one episode, Ami and Yumi harshly try to sic them on him.
Unintentional Uncanny Valley: For Vlad’s first design, he had realistic teeth, which is jarring compared to his cartoony feel. This was fixed by his second appearance by replacing the realistic teeth with fangs.
Unexpected Character: The Talent Suckers' cameo appearance in "Puffy B.C.". That episode took place entirely in the pre-history and they only appear because of a never seen before (or since) Time Machine.
