favourite sonic headcanon?

I have a certain spin on the 'hedgehog quill hammerspace' headcanon that draws inspiration from the myth that hedgehogs roll around to collect mushrooms and berries and whatnot in their quills; lots of Eastern European art exists, for example, which depicts a hedgehog carrying an obscene amount of things in its quills as a way of gathering food.

My headcanon is that the sonic characters with quills store things by spearing them on their quills, rather than just hiding them in 'pockets' by their head (although I figure it would be a mix of both since some stuff would be 'unspearable', such as a chaos emerald; in that case the surrounding things speared into their quills would be what would hold the emerald).
