My headcanon was that Derpy's mom is Daring Do. Derpy changed her name from Ditzy Do ever since her mom's books became too famous. Derpy was also never allowed to go on any treasure hunting missions ever since that one temple that exploded, imploded, flooded with snakes, and caught fire within 15 seconds of Derpy 'accidentally' stepping on several suspicious looking stones.
