* Almost everytime the action version of "Legend of Mermaid" is sung by the girls is a moment of awesome.
** The best part is watching the villian of the moment cringing in pain becuase of a song and ultimately beating a retreat ([[CrowningMomentOfFunny nearly always throwing a hissy fit about it.]])
* ''MermaidMelodyPichiPichiPitch'': Coco can use her powers ''without'' her pearl, not sound HollywoodToneDeaf or cause property damage, and get to Sara despite being in a [[PeopleJars Person Jar]] for most of the arc. Sadly, this, [[OutOfFocus plus everything else Coco is ever important in save for one filler episode]], is only in the manga.
** The anime made up for it when, instead of [[spoiler:the Black Beauty Sisters being [[ImAHumanitarian eaten alive]] before they can react, they proceed to do a HeelFaceTurn, use Michel's powerups on themselves, and trap him in their own music bubble. Before they die, they are probably the first to land attack damage on him, and they're using their [[SoLastSeason song from last season]]]].
