There's a mare who battles freaks of nature
She goes where the whim of Celestia takes her
'Til something went astray, and the bugbear got away
It just might catch up with her tomorrow
Secret Agent Mare, Secret Agent Mare
You've gone deep undercover,
and had to change your name
While hiding out she met the pony Lyra
Who stirred confusing feelings deep inside her
She had to just pretend
That they were the best of friends
Nopony needs to know about her sorrow
Secret Agent Mare,
Secret Agent Mare, Secret Agent Mare
She can't reveal she wants her,
so she has to hide her pain
Secret Agent Mare,
Secret Agent Mare, Secret Agent Mare
Discovered by the monster,
and you're out the windowpane
The bugbear showed up in Ponyville one day
She explained it all then left to keep her friend safe
Oh yeah, she gave that bear the slip
The Mane Six took care of it
And now she can relax and cheer the burro
Secret Agent Mare, Secret Agent Mare
They took care of the monster,
now you can let down your mane
Secret Agent Mare!
