!! Both ''[=PaRappa=]'' and ''[=UmJammer=] Lammy'' examples:
* SugarWiki/AwesomeMusic: [[AwesomeMusic/PaRappaTheRapper Has its own page]].
* EarWorm: Pretty much any song in this game series.
** Kick! Punch! It's all in the mind...
* EnsembleDarkhorse: Chop Chop Master Onion.
** Also, Hairdresser Octopus (among female players)
* FanPreferredCouple: [=PaRappa=] and Lammy, despite the fact that both [=PaRappa=] games focused on [=PaRappa=]'s love of Sunny.
** Some fans {{lampshade|Hanging}} this by showing that Sunny is [[LoveTriangle not amused]].
** And it doesn't help that at ''[=PaRappa=] 2'''s final stage, [=PaRappa=] is singing to Lammy, who's playing with him on stage, while Sunny is just watching from the audience with her father.
* NightmareFuel: [[EverythingsSquishierWithCephalopods Hairdresser Octopus]]. Mainly his [[RunsWithScissors scissors-flailing]] [[JekyllAndHyde crazy side]].
** Don't forget [[http://www.youtube.com/watch?v=tU5kBlENd_0 Cathy Piller]]!
** Teriyaki Yoko. Especially when you fail and she rises out of the ground, 100 times her size. Even in the American version.
*** The "Taste of Teriyaki" song itself. There's a reason it's under LoveItOrHateIt below; the whole thing just sounds otherworldly and threatening, [[PlanetHeck which is very fitting for the stage]]. And [[https://www.youtube.com/watch?v=p8irurO5ru8 the MilkCan: Make It Sweet remix]] makes it even ''more'' terrifying.
** There's something about the sunset scene Stage 5's cutscene that's very spooky and unsettling... The color error and animation could be suspect.
* ParentalBonus [=/=] FridgeBrilliance: Benito Mussolini --> Instructor Mooselini.
* ScrappyLevel: The fifth level in the original (thanks to a sudden DifficultySpike in having to out-rap every previous Master) and the sixth level in ''Lammy'' (while not as difficult to play by itself, some people find the background music for the level to be simply god-awful).
* SuspiciouslySimilarSong: In ''[=PaRappa=] 1'', "[=PaRappa=]'s Live Rap With MC King Kong Mushi" sounds a little like the rap version of "[[http://en.wikipedia.org/wiki/December,_1963_%28Oh,_What_a_Night%29 December, 1963 (Oh, What a Night)]]" by Music/FrankieValliAndTheFourSeasons.
** The cinema before the fourth level includes a short ditty that sounds remarkably like the song "Tijuana Taxi".
** The driving lesson song is a pretty blatant ripoff of "Turtles Have Short Legs" by Can.

!! ''[=PaRappa=]''-only examples:
* BigLippedAlligatorMoment: Level 7 of ''[=PaRappa 2=]'' has DJPJ's booth crashing through the wall and causing a power surge. The level then continues as if nothing happened.
* FamilyUnfriendlyAesop: According to Prince Fleaswallow, "Money money money is all you need."
* SugarWiki/{{Funny Moment|s}}: The Bathroom Rap... PERIOD.
* StopHelpingMe: Boxy Boy's tutorials in ''[=PaRappa 2=]'', which interrupt cutscenes and can't even be turned off for the experienced players.
** [[spoiler: That is, unless you press the start button.]]
* ThatOneBoss: Potentially, ''any'' of the bosses, but [[MeaningfulName Cheap Cheap]] the Cooking Chicken is consistently hard for a lot of people.
* ThatOneLevel: The bathroom rap level is considered to be extremely frustrating due to how many buttons the player has to play back with near perfect timing in order to succeed. This was probably one of the reasons why the sequel has a more forgiving mechanic for button pressing in the levels.

!! ''[=UmJammer=] Lammy''-only examples:
* AnimationAgeGhetto: See "WhatDoYouMeanItsForKids"
* BigLippedAlligatorMoment: After Lammy has eaten too much pizza and tries to run but collapses, a parade of expectant bunny parents led by Cathy Piller marches out of nowhere and sings a brief version of "Treasure", which describes that BabiesMakeEverythingBetter! This gets us all like "WTH?"
** [[LampshadeHanging Even Lammy is confused by it.]]
* LoveItOrHateIt: Depending on who's listening, "Taste of Teriyaki" is either one of the [[AwesomeMusic/PaRappaTheRapper best]] songs in the series, or the ''[[HellIsThatNoise worst]]''.
* ThatOneLevel: Many players have the toughest time with Cathy Piller or Teriyaki Yoko. The former gets [[BreakingTheFourthWall lampshaded]] in the game.
---> '''Rammy''': "I hate this stage!"
* WhatDoYouMeanItsForKids: At least in the European version, where PEGI gave it a ''3+'' for [[http://www.pegi.info/en/index/global_id/505/?searchString=lammy "violence that is set in a cartoon, slapstick, or childlike setting"]] due to Stage 6 [[spoiler:being that, like in the Japan version, [[YouCantFightFate Lammy has died due to a]] BananaPeel [[YouCantFightFate accident and ended up in hell,]] where Teriaki Yoko sings about {{Satan}}, his [[HornyDevils wanting to hook up with her, and her wanting to have dinner with him]], [[DreamingOfThingsToCome as foretold by Chop Chop Master Onion in her dream sequence]]]]. The U.S. version thankfully averted this by {{bowdleris|e}}ing the entire Stage 6 to make it "kid-friendly", for fear that it would get a "Teen" rating if it were unaltered.

!! Anime-only examples:
* CreatorsPet: A awful lot of the episodes center on anime-only character Paula.
* SugarWiki/HeartwarmingMoments: The Christmas Special is considered to be the most touching episode of the series by fans.
