“What once was lost, so as to be found;
may your stitched mouth be unbound.
Four hooves of cotton, stuffing, thread;
may they gallop and touch, tail to head.
Eyes once of buttons, so that you can see;
to you, my lost friend, a simple task: be."
Twilight misses her longtime companion, Smarty Pants.
So she decides to bring her back the only way she knows how: by using magic.
After all, if you can't find a friend, why not have that friend find you?
Right?
... right?
