As some of you may know, Sonic can’t swim, and the reason why is rather peculiar. Yuji Naka – one of the game’s original programmers – simply assumed that hedgehogs couldn’t swim, so he wasn’t about to let Sonic do it either. Essentially they were cool with him running at the speed of light but swimming was out of the question. Rather embarrassingly, it turns out that hedgehogs are rather excellent swimmers. Woops.
