Translation:
 
“When Ah was a li’l girl, i really liked ponies.
 
I used to play with them and pretended to be one of them.
 
Granny Smith said i could easily be mistaken for one of them.
 
So they started to call me “Background Pony” and it became my family nickname.
 
Apple Bloom likes to call me that when she believes that i’m getting conceited.
 
Well, but such is family. You’ve got to accept the sweet and the sour.”
