* In the first episode, Luchia tries to sing a song, except she's horrible at it since according to Hippo, [[HollywoodToneDeaf Mermaids who don't have their pearls have no sense of music]].
* Watching the villain of the moment cringing in pain because of the Mermaids songs and ultimately beating a retreat. [[JekyllAndHyde Eriru's]] hissy fits are some of the best.
* There's a rather funny episode where the reformed Dark Lovers make a comeback, and cause nothing but chaos. They even have a CatFight, throwing shoes and walls of water at each other.
* Hippo singing "[[http://www.youtube.com/watch?v=6PIuqz4NBzw Legend of Mermaid]]".
