Fun Fact:
According to an off-the-record conversation with Lauren Faust, Scootaloo was originally created to be a handicapped Pegasus who couldn't fly (for reason unknown.)
She was going to use Scoots for the lesson "Embracing what you're good at, even if it's not what you want." (Paraphrasing)(She's good with a scooter, even though she idolizes RD and wants to fly with her.) Could also be used as a "Never give up on your dreams"-type of lesson.
I would be okay if they chose to follow up with this idea for Scoots.
