[Pinkie Pie]
It's your birthday party, a very special day
I've got a song, it won't take long, I just wanted to say
Happy, happy, happy, happy
Happy, happy, happy, happy
Happy, happy, happy, happy birthday to you!
[Cheese Sandwich]
If you wanna be the life of the party
But you're feeling just a little uptight
Call the doctor, beg and plead
"Doctor, tell me what I need"
Try to put a little cheese in your knees!
[Pinkie Pie]
Bubbles and balloons, bubbles and balloons
What's a birthday party without bubbles and balloons?
Star-shaped or trapezoid, look what I can do
Only Pinkie Pie can make a bubble shaped like you!
[Cheese Sandwich]
Just let yourself go floppy, for now this is your chance
Pretend you have no bones and do [bad word] chicken dance!
Hit it, Boneless!
[Pinkie Pie]
Cooler than [bad word] chicken and tastier than [bad word] on, you, let's party down and do the Gummy shake!
Hit it, Gummy! Uh-huh! You know it! Shake it!
[Cheese Sandwich]
'Cause I like to make you smile, smile, smile
Yes I do
It fills my heart with sunshine all the while
Yes it does
'Cause all I really need's a smile, smile, smile
From these happy friends of mine
Pinkie Pie: That's my song!
Cheese Sandwich: What do you mean? I have no idea what you're talking about.
Pinkie Pie: THAT'S IT!
[Pinkie Pie]
Roll out the party cannon
When you hear the party cannon song
Ka-BOOM!
[Cheese Sandwich]
Why should [bad word]  Try this one on for size
'Cause nothing quite says cheer like the ringing in your ear
Of the cheese supreme cannonball surprise!
[Pinkie Pie]
¡Dale, dale, dale
No pierdas el tino
Porque si lo pierdes
Pierdes el camino!
