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.

Happy bday!

Yay! We're here, everypony!
Phew, that wasn't long. I told you we could easily make it on hoof!
Speak for yourself, Twi, you didn't have to carry this cake! It's heavy, you know!
Thank you for helping out, Dashie! I couldn't have settled for anything less, after all!
Hi... We're here to... wish you a happy birthday.
You said it! Happy birthday!
And what better way to say "happy birthday" than with a cake?
Why, with a real Apple family apple pie, of course!
With a muffin! Yay!
But these, while pleasant to give, mean little by themselves...
What makes them meaningful are our wishes for you!
Exactly! And we wish for you to have a perfect birthday and a great year ahead of you!
Don't fear any challenges you might face! No matter how bad it may seem, have faith in yourself and keep on being awesome!
And while at it, keep a level head and don't lose sight of what's important! Keep the magic of friendship alive in yourself!
Remember your loved ones and friends, an' don't let little things an' worries get you down!
We hope that you'll find all you seek and be the best you can be!
Don't forget to respect yourself! You're the best at being you, so stay true to what you really are!
And we hope that you'll be at peace with yourself, too... and that the year ahead will be peaceful for you.
And throughout all that, have fun! It isn't fun if you don't have any, after all, and fun it should be!
Just like today! Party on!
