Rhythm Tengoku
Tap Dance consists of the following versions in Rhythm Tengoku:

Unused Content
Version 05 of Tap Dance does not have any graphics specifically made for it; instead it randomly selects one of the other versions when loaded. It is used in an unused version of Tap Dance, which is mostly the same as the final version, but has extra patterns in the middle, and curiously uses the jingle at the end of Karateka's music. It cannot be accessed through Sequence Test.

Every version of Tap Dance in Rhythm Tengoku has animations for every move in the game, despite most not being needed.

Every version of Tap Dance in Rhythm Tengoku has sprites for the Giraffe, most of which go unused. The Giraffe is replaced with a dragon in the Remix 7/Remix 8 version of the game, and a camel in Super Tap. Remix 5 is the only version to not have any sprites for the Giraffe. In Rhythm Tengoku (Arcade), the outline of the platform in the second section of Tap Dance is miscolored magenta. This error is not present in the GBA version of Rhythm Tengoku.

Unused Content
Tap Trial 2 contains a remade version of the Camel from the original replacing the Giraffe, still unused. Interestingly, the camel's legs can be seen on the prologue to Tap Trial 2 in Rhythm Heaven Megamix, replacing the giraffe's.

Miscellaneous
In the Wario...Where? version of Tap Trial, Ashley makes a generic miss sound when failing on a jump, unlike the Girl who has unique voice clips.
