Howdy there, friend!
We're here today to wish you a happy birthday!
I'm so excited to do this! Rarity told me how fun it can be!
Dash said how important it is for us to greet our friends in the other world! It's an honour!
Focus, girls, remember how we practiced it...

We wish you all the best on this occasion! May you have lots of happy times and good things come your way!
And we wish you'll be able to do your best for yourself too! And, and...
And stay in good health and high spirits all the time! And believe in yourself and who you are!
An' also we wish you great friendship and to have your nearest an' dearest with you to share in the good and deal with anything bad together!
So on behalf of all Equestria we wish you...
Happy Birthday!
We did it, girls.
Now let's all celebrate! Cue the music, Scoots!

A very good day to you, human. I come to you on your day of birth with greetings... and thanks.
My good subject Pinkie Pie told me she had taken to congratulating some humans on their birthdays, but even she has her limits. So she asked us for a bit of assistance... and for such friends of ponykind, we feel it right to provide it.
It is thanks to people like you that our land of Equestria, our very world, exists like it does. It is your friendship with us that gave us life. For that, we will forever be grateful and cherish you.
And so, allow me to wish you happiness, peace, prosperity and fulfillment! My hope goes with you that you suffer no hardship in the year ahead, but should a challenge befall you, I am certain your courage and skill will see you rise to conquer it!
Now... where is she...
Here, sister!
Fashionably late, I see! But just in time for the greetings to be given.
Right! I'm ready. Three, two, one...
Happy Birthday!
And now... let us commence the royal party.
