Ouroboros Spine if you scratch my back

When he charged into the thicket, he came out with a rabbit, squealing as it hung from his jaws before he crushed its skull between his teeth. But the thicket had also bestowed upon him another gift: burrs. Burrs that threatened to replace his fur coat with one made entire of clingy, spiky spheres. It took him the better part of an hour to groom himself while his breakfast cooled off to the side. His teeth plucked burrs from his legs, his chest, from his flanks and tail. But he could not reach a clump that had lodged on his back, between his shoulders.

Kodiak rubbed himself against a tree, rolled, and tried to hook the burrs with a back paw, but he succeeded only in crushing the burrs and causing them to settle deeper into his grizzled brown fur. Now every ripple of his muscles made his nose twitch with irritation, as the burrs pricked his skin, like the claws of some tiny gremlin. His ears fell flat against his skull, and a growl rumbled in his throat as the brown bear sank to his haunches. Left to contemplate this annoyance, and how he might rid himself of it.
