(Note: Sung to the tune of Mulan's "True To Your Heart")

Sung by Rainbow Dash

One day, Rainbow Dash announced to every pegasus in town that Ponyville's reservoir had been picked to supply Cloudsdale with the water for the entirety of Equestria's rain for a year— and the only way to move all that drink was to mak a tornado that could make enough lift to get it all to Cloudsdale.

If anypony needed to know how strong, Twilight Sparkle's handy-dandy graph would give the answers. A least, if you knew maths, anyway.

Ponies, I knew at once that we have a job here
Deep in my soul, I know that we must get in gear
Though you're unsure
On how to move
The reservoir
To Cloudsdale by hooves

Ponies, I see your future, despite all the murk
I know that we must get eight hundred wing power to work
But I’d rather beat
The record of
A thousand wings
Of power above

True to your chart
You must be true to your chart
Any less and we fall apart
And, ponies, we can’t make enough lift
Open your eyes
Your chart can tell you no lies
And when you're true to your chart
I know it's gonna lift the water up

Not even seven hundred and ninety nine
And Celestia knows how many bits isn’t fine
We need the wings that we can get
Just trust your chart
And the deadline’s met!

True to your chart

Girl, my chart is telling me to synchronize
All the pegasi should in one direction fly
You check the graph
You’ll know the speed
You won't get stuck
With your chart to guide you

True to your chart
You must be true to your chart
Any less and we fall apart
And, ponies, we can’t make enough lift
Open your eyes
Your chart can tell you no lies
And when you're true to your chart
I know it's gonna lift the water up

True to your chart
You must be true to your chart
Any less and we fall apart
And, ponies, we can’t make enough lift
Open your eyes
Your chart can tell you no lies
And when you're true to your chart
I know it's gonna lift the water up

True to your chart

So let’s make this tornado!
If you don't know where to start
Just check back on your graph and
Just be true to your chart
Now go home, stretch your wings or
We’re doomed right from the start
Don’t forget, take the graphs home
Just be true to your chart
True to your chart
