* EarWorm: "[[http://www.youtube.com/watch?v=8CB1fFeb1n8 Fever]]" and "[[http://www.youtube.com/watch?v=RsBtQCDbTWc Chill]]" by Creator/HirokazuTanaka.
* NightmareFuel: [[NightmareFuel/SuperMarioBros As usual]], here we have the GameOver [[http://www.youtube.com/watch?v=7u6TsEutA4M music]]. It starts off [[ScareChord in a chilling way]] and then [[HellIsThatNoise it doesn't get better, either]]. It's [[IncrediblyLamePun chill]]ing.
** [[DepartmentOfRedundancyDepartment "Chill," too.]]
* NintendoHard: Once you reach the later levels, it can be hell trying to organize pills with over half the screen being filled with viruses.

* SuspiciouslySimilarSong: "Fever" for "Lady Madonna" by Music/TheBeatles.
* UglyCute: The viruses. Except for Chill, who could arguably just be cute.
