How
Daffy Duck responded to
the bear's sway-mooning him after crossing over to the other side of the hunting-boundary --- i.e., he was offended by the bear's cheekiness, and so he fired some shots in the bear's direction at the next chance he got.
Example:
Shortly after Daffy Duck performed the whole, "
Grizzly's got a booty like --- POW! POW! POW!" routine, he did indeed manage to score a glancing hit on
the bear's butt and blow off a patch of fur, so the bear vengefully stuffed
Daffy's beak full of shotgun-shells and catapulted him through the air so that he slammed head-first into a tree, setting off the shells one by one and causing massive jets of flame to blast out of Daffy's mouth for some time afterwards.
