Shredder:

You want to go outside? Why, Karai,
Look at you, as fragile as a flower
Still a little sapling, just a sprout
You know why we stay here in the hideout

Karai:
I know but

Shredder:
That's right, to keep you safe and sound, dear
Guess I always knew this day was coming
Knew that soon you'd want to leave the nest
Soon, but not yet

Karai:
But

Shredder:
Shh!
Trust me, pet
Father knows best

Father knows best
Listen to your father
It's a scary world out there

Father knows best
One way or another
Something will go wrong, I swear

Ruffians, thugs
Poison ivy, quicksand
Cannibals and snakes
The plague

Karai:
No!

Shredder:
Yes!

Karai:
But

Shredder:
Also large bugs
Mutants with pointy teeth, and
Stop, no more, you'll just upset me

Father's right here
Father will protect you
Darling, here's what I suggest

Skip the drama
Stay with papa
Father knows best

Father knows best
Take it from your daddy
On your own, you won't survive

Sloppy, underdressed
Immature, clumsy
Please, they'll eat you up alive

Gullible, naive
Positively grubby
Ditzy and a bit, well, hmm vague
Plus, I believe
Gettin' kinda chubby
I'm just saying 'cause I love you

Father understands
Father's here to help you
All I have is one request
Karai?

Karai:
Yes?

Shredder:
Don't ever ask to leave this hideout again.

Karai:
Yes, Father.

Shredder:
I love you very much, dear.

Karai:
I love you more.

Shredder:
I love you most
Don't forget it
You'll regret it
Father knows best
