And as it so happens that's also more or less what Ruffnut's experience is. I expect she'll climb on it's back and get tossed around. Maybe with his help she can get the bear to actually ram into a tree and they are both in shock that they actually killed the thing just by being clumsy fools?

Or alternatively they could blind the thing sending it running away only to come back for revenge like that bear in Brave.

Or alternative to that alternative the two morons could wrestle and get chased by a bear and get stuck in a tree while it roars and them and tries to shake them down.

Or something else entirely.
