Most of the Rhythm Heaven soundtracks are Japan-only, so the localized versions of the vocal songs are hard to come by they also don't have extended versions like the Japanese ones do.
I Knew It!: This promotional video for WarioWare Gold reveals that the boy in Kung-Fu Ball is indeed Young Cricket, which was a common fan theory among fans prior.
The series' producer and primary composer, Tsunku♂, was also a long-time producer for the Hello! Project. It's no coincidence that the development team also made WarioWare. While most of the text is translated, the voice samples remain untouched (a fact joked about at least once), though it was planned to at one point. Fan Translation: Tengoku was given a translation by a fan named "W Hat" titled "Rhythm Heaven Silver". Fan Remake: Karateka Mania, which is a remake of the Karate Man games (the DS version in particular), retooled as a more traditional rhythm game. Megamix had a bootleg mobile port which can no longer be accessed, presumably due to potentially obvious reasons. One of the many web browser games Adventure Time had was called Rhythm Heroes whose Rhythm Games mostly consisted of Expies of existing ones like Glee Club. There's an obscure Nintendo DS game called Beat City which has you hold the system on it's side like Heaven, and whose protagonist bears a striking resemblance to the Munchy Monk. Follow the Leader: While not nearly to the same extent as Mario Party, Wii Sports or even WarioWare, Rhythm Heaven is still a Minigame Game owned by Nintendo that gets a few clones here and there. All subsequent games were again developed by Nintendo SPD. A year later, Sega developed the arcade version. Channel Hop: Nintendo SPD developed Tengoku. Ascended Fanon: "First Contact" was a Fan Nickname created well before Megamix received an official translation. Ko Takeuchi, the lead character designer for the series, left an appreciative comment on the "Rhythm Heaven Reanimated" Multi-Animator Project, reading, "Thank you from the bottom of my heart.". Although Nintendo initially thought Sega was joking when they proposed the arcade version of Tengoku, they eventually gave their approval towards the port once they realized that they were serious and how much Sega's staff loved the game, with Iwata being ecstatic about the idea.
