Fridge / Rhythm Heaven

Fridge Brilliance
  • Several Rhythm Heaven characters make appearances in Game & Wario, from the Chorus Kids being backup singers for Sal Out, to the Wrestler and Interviewer Girl appearing on the sidewalk in the Pirate minigame's opening. Additionally, the male character in Fever's Kung Fu Ball very heavily resembles Young Cricket from the WarioWare series, the only difference being the hair color (which is grey as opposed to Young Cricket's black and white, but what does black and white make?). This opens up the possibility that the Rhythm Heaven series is set in the same universe as the Mario series. ...Which also means that the cast of Rhythm Heaven (along with the other Mario-related series such as Donkey Kong Country and WarioWare) was also affected by the events of Super Mario Galaxy and Super Paper Mario climaxes.
  • Left-Hand Remix in Megamix is, like the other end-of-game remixes in the franchise, a series of surreal scenes that play out one after another without any logical connection between them but is treated as if it's all perfectly natural. Such a thought process makes complete sense taking into account that it's All Just a Dream. Bearbara might be getting a fever.
  • What looks like a little slit right below Tibby's neck might appear to just be a spot, a fold, a bow-tie or some kind of weird shading might actually be something more. If what he grows up to be is anything like his mother, that is most likely a rhythm stage in development inside of him.
  • Look at the order of each stage in Megamix. The order of the four games every time (before the remixes) go from Tengoku (GBA)—>Heaven (DS)—>Fever (Wii)—>an original game in Megamix (3DS), and the pattern just keeps on repeating.

Fridge Logic
  • A deliberate example with "Cheer Readers." The concept itself is silly enough ("academic cheerleading," basically), and then you remember that the pep squad is shouting encouragement in a library.
