It has been asked what is special about an earth pony.
Uniponies have their magic,
Pegasi their heads in the clouds and wings to keep them there,
But what of the earth ponies?
Why they have nothing and everything,
You'll never get one to brag,
Those that are the foundation and glue of Equestria,
Who consider themselves but a stitch in the fabric of Equestria.
What's special is not what they have, but what they were given,
They are born with their hoof on Equestria's heart,
They spread her seeds, and she warns them when to tread carefully,
They care for her, and she rewards them with jewels and other valuables.
Earth ponies have no specialty, but rather they care for Equestria so she might care for all of her children, that is their duty and their reward.
