Please indent by 4, not 2 characters.  It's very hard to see what's
lined up with what.  And that's compounded by having the line numbers
there so that the first 9 lines are shifted left.

Those lines have compound if conditions.  Line 8 will be true/true
only the first time you type "taunt bear".  Notice the operator "not" in
front of bear_moved.

Line 12 will be true/true only if you've already run line 11.  Since
bear_moved = False initially, the only way you get true /true here is by
answering "taunt bear" twice.
