If you’re a fisher, i.e. a North American Marten, i.e. a mustelid relative of the weasel (and the mink and the ermine and the stoat and other cute animals) – you hop over the porcupine a whole bunch of times, causing it to spin around again and again until it becomes woozy. Then you claw its face until it bleeds out. Then you flip it over and eat it. (Not so cute after all.)
Curiously, fishers don’t eat fish.
