The Tall Tappers are also pretty popular characters despite their minigame only appearing in Fever, for similar reasons as DJ Yellow (having a happy, fun-loving personality).
Fanon: The music in Heaven's Love Lab and Megamix's Pajama Party are extremely similar, especially the singing in the two.Their similarity to the also popular Space Dancers/Paddlers also help. 'Donk Donk' has one of the most bizarre concepts for a minigame, as it deals with an octopus commanding rhythm-electrodes to make a rocket fly.Thus, it's a popular fan theory that the girl in Pajama Party is the child of the couple from Love Lab. One minigame in Fever is called 'Cheer Readers' and revolves around a group of girls who encourage other people to read more books.This weirdness extends to the rhythm itself: it focuses primarily on triplets (Dit-dit-DAH dit-dit-DAH), which are rarely used through the rest of the game.
Good Bad Bugs: At least in Megamix, Quiz Show is the only game where you can flunk out through the tutorial.In a stereotypical Engrish speech, the word 'Cheerleader' would be pronounced as 'Cheer reader'.
