I was chilling in Equestria late one night
When my eyes beheld an eerie sight
For the monster in the moon, began to rise
And suddenly- to my surprise!

She did the mash! She did the pony mash!
The pony mash! It was a nightmare night smash.
She did the mash! It caught on in a flash!
She did the mash! She did the pony mash!

From my library, to the castle east
To the darkened caves where the batponies feast
The mares all came from their humble abodes
To catch a peak at the next episode

They did the mash! They did the pony mash!
The pony mash! It was an equestria smash!
They did the mash! It caught on in a flash!
They did the mash! They did the pony mash!

The crystal kingdom was having fun
The party had just begun
Guests included Celestia- the princess of the sun!

The scene was rocking! All were digging the sounds!
The timberwolves were baying like hounds
The Ursa Major was about the arrive
With her vocal group- the bear attack five!

They played the mash! They played the pony mash!
The pony mash! It was a lunar smash!
They played the mash! It caught on in a flash!
They played the mash! They played the pony mash!

Out from her kingdom, Chrysalis voice did ring
It seems she was troubled by just one thing
She broke down the door, and screamed from the maranda
Whatever happened to the changeling lambada?

It's now the mash! It's now the pony mash!
The pony mash! It's an equestria smash!
It's now the mash! It caught on in a flash!
It's now the mash! It's now the pony mash!
