Rainbow Dash kicked at one of the apple trees, halfheartedly. To absolutely nopony’s surprise, nothing happened - partially because she put no effort into the blow, but mostly because there were no apples left to harvest.
Satisfied by her minor act of frustration, she went back to ploddingly walking over every hill to see if she could find anything else that might have been left out.
“Ugh, this would go so much faster if you let me fly...” she complained.
