I adore Tails's Act 2 victory spin-fail (Like at 02:48 & 11:58), for he's so ecstatic during his pop-off, that he then becomes so distraught upon realizing he somehow lost enough balance to fall on the ground, butt-first, for no apparent reason. Him impressively immediately regaining enough composure, after the embarrassingly unexpected rear-first landing, to either scratch his head/ear (Can't tell which) or pump his fist, while appearing practically unfazed by the sudden fall, just moments ago, aside from a potential tinge of confusion over how exactly he wound up sitting on the floor (Why does he remain seated with a tilted head while fist-pumping or ear/headscratching, going into the fade-to-black, instead of getting back up, anyways?) is admirably awe-inspiring.
