Pinkie Pie and Rainbow Dash become new friends after Dash discovers Pinkie is into practical jokes. But their new friendship is tested by the return of one of Rainbow Dash's old friends from Junior Speeder Flight Camp, Gilda the Griffon.

And is the nature of a good prank inherently evil? Find out in this week's Brony Quest.
