It's always fun to realise that all your favourite childhood characters are completely disgusting creatures. Like Sonic the Hedgehog, who in real life can run really, really fast but would also create foam poop with its mouth to rub it on itself for no reason at all. In fact, hedgehogs love all kinds of poop.
Plus, his best friend totally wants to eat him. Childhood memories are best ruined by hilariously gross scientific facts.
