Unused Content
According to the debug menu of Rhythm Heaven Megamix, a short version of Flock Step was planned. This is further supported by the existence of strings for the short version's Rhythm Item in Rhythm Tengoku: The Best+'s data, though they are mostly blank. The one string that is present is virtually identical to the equivalent in the long version. There is also an empty group file for its music, labeled "GROUP_WSD_KANTORING_SHORT.bcgrp".
The debug menu also contains a reference to RVL鳥の大群02 (rvl_birds_02?), suggesting the presence of an arrange version of Flock Step, being after the unused short and used long versions. However, with the entry being labeled with a number rather than a letter, there being no pre-existing arrange version of Flock Step and no other data anywhere for this version, this entry is most likely the result of the developers copy-pasting and simply not removing the excess entry.
