[Intro 1: Dad, (Young Girl)]
(Hey, Dad? What's puberty?)
Okay, well, let my try my best to explain it to you
See, puberty is a process, and it makes everybody feel strange
Because that's when you start getting more mature and your body goes through a change
It's how a girl grows into a woman, it's how a young boy becomes a man
Don't worry, honey, it'll happen for you soon, and you'll understand
(It'll happen for me soon? How soon am I supposed to go through puberty?)

[Intro 2: P.T. Barnum, (Girl)]
Right about now! Hooah!
(Who are you?)
Name's P.T. Barnum! The P stands for Puber! And I'm the ringleader for the greatest show on earth!

[Verse 1: Barnum, (Girl)]
Welcome to the jungle, we're the hormone gang
Delivering sexy messages between your ovaries and your brain
And I'm the only one that knows exactly what you need
(I need to get out of here!) Sure you do, but you won't till you're fifteen!
In the jungle, look into the jungle
It's right there, between your
Sha na na na na na na na na, knees, knees!
Just wait, kid, once a month that thing will bleed!

[Verse 2: Acne]
Welcome to the jungle, I'm the acne on your face
You can try to get rid of me if you want, but I pop up all over the place

[Breasts, (Girl)]
And we're your budding breasts (you are?)
Look, kid, we're still growing in size

[Barnum, (Girl)]
(And what's that smell?)
That's you!
(Me? P.U.!)
[?]
In the jungle, welcome to the jungle
Here to keep you humble
(Does this happen to boys, too?)
Sure does! It's gross as hell!
(What happens to them?)
Their serpentine starts to swell!

[Bridge: Barnum, (Girl)]
(Ugh, I hate it here! I suddenly feel terrible!)
Yup! That's called a mood swing, kid, get used to those!
Sometimes in the jungle you feel so high
Then your mood will swing down
(Oh no!)
Further down
(Oh no!)
Then back up
(Oh phew)
Until it goes down
(Oh no!)
[beeping sound]
Oh, I'm picking up a strong signal from the brain
(What does that mean?)
Someone's got a crush!
(What?)
(Crush, crush, got a crush)
Ha ha ha!
(I have to get out of here!)
You can't escape us!
You're in the jungle, baby!
When you see someone you like, you're gonna die!

[Finale: Barnum, (Girl), Hormones]
In the jungle, welcome to the jungle
Don't just whine and grumble
We're here to help fill your needs, needs
Oh, the jungle, take care of that jungle
Get some antifungal
(Antifungal what?) It's cream, cream!
For your jungle, everywhere's a jungle
Armpits, ear [?]
You don't have to take it from me!
Hormones, harmonize!
In the jungle, welcome to the jungle
(You're a little flat)
So are you!
It's gonna bring you down!
Wow-ah!
