Samurai Slice/Unused

Rhythm Heaven
Samurai Slice consists of the following versions in Rhythm Heaven:

Unused Content
There are unused sprites in this game, depicting the Ninjas from Ninja Bodyguard, and Tiny Ninja from WarioWare, Inc.: Mega Microgame$!, who appeared in the microgames Stick & Move, Arrow Space and Ninja Vision. Some of the sprites from these microgrames (such as the rock and tree in the background, along with the general aesthetic) were reused directly in this game.

Regional Differences
The Wandering Samurai has a different appearance in Rhythm World, his clothing looking like a "pojol" (Korean police during the Joseon period). He was also given a beard. Samurai Slice in Rhythm Heaven Fever and Super Samurai Slice in Rhythm Heaven Megamix also got redesigned characters, though The Wandering Samurai wears a headband instead of a hat and lacks the beard in those appearances.

Rhythm Heaven Fever
Samurai Slice consists of the following versions in Rhythm Heaven Fever:

Unused Content

 * During Samurai Slice's story cutscene, the last screen shows The Wandering Samurai leaving to retrieve the pinwheel as Pinwheel Girl and the other child stay behind. This scene has two different lines shown on-screen, reading Don't Worry. (そこで まっておれ) and I will see justice done. (おじさんに まかせなさい). In Minna no Rhythm Tengoku, there is a third line which goes unused: 夜勤おけなのに きついなあ (Although my night shift is finally over, it's quite tough). This line has a single sprite using it, followed by duplicates of the other two, without any miss variants. This third line was removed entirely in all other languages, with the unused sprites simply left textless.
 * Likewise, Samurai Slice 2's final story cutscene has two different lines, those being Save my bunny! (取り返して！) and Buy me a new bunny! (新しいの買ってきて！), with an unused third line in Minna no Rhythm Tengoku, being だから、あなたは誰？ (So, who are you?). There is no unused sprite for it, however.

Regional Differences
In Rhythm World Wii, the characters featured in this game have their traditional Japanese clothing altered to resemble Korean traditional clothing, called Hanbok. Interestingly, The Wandering Samurai's appearance is different from that of the Samurai Slice in Rhythm World. Additionally, in the Superb epilogue, the colors of the background were changed from red and yellow to blue and cyan.

In the background of Samurai Slice, the snow layer on the mountain in the background was removed in Rhythm World Wii (presumably to remove the resemblance to Mount Fuji), however this change was oddly not represented in Remix 8, nor in the game's reapparance in Rhythm Sesang: The Best+.

In Samurai Slice 2, the the sign over the door in the bottom right was changed in each version, most notably the removal of a wine glass on the sign. Rhythm World Wii gives The Wandering Samurai a new appearance here as well, going from a lightning-based rework of his normal outfit in other versions to a new outfit with a hat decorated with lightning blots, and sporting the beard once again.

Rhythm Heaven Megamix
Samurai Slice consists of the following versions in Rhythm Heaven Megamix:

Regional Differences
In Rhythm Sesang: The Best+, the same changes as in Rhythm World Wii apply, with the exception of the altered mountain in the background. Interestingly, the Official Game Trailer doesn't use the localized artwork for this game.
