Disclaimer: I do not own any songs this is parodying or characters. This is 1987 cartoon btw. I thought it fit the 80s cartoon really well.

I never thought mutants essential
They're crude and unspeakably plain
But maybe they've a glimmer of potential
If allied to my vision and brain

I know that your powers of retention
Are as wet as a warthog's backside (Bebop) hey!
But thick as you are, pay attention!
My words are a matter of pride

It's clear from your vacant expressions
The lights are not all on upstairs
But we're talking power and successions
Even you can't be caught unawares!

So prepare for a chance of a lifetime
Be prepared for sensational news
A shining new era is tiptoeing nearer

(Krang)

And where do we feature?

(Shredder)

Just listen to teacher
I know it sounds sordid but you'll be rewarded
When at last I am given my dues!
And in justice deliciously squared
Be prepared!

(Rocksteady)

Yeah! Be prepared, we'll be prepared! For what?

(Shredder)
For the death of the turtles

(Rocksteady)
Why are they sick?

(Shredder)
No, fools! We're gonna destroy them and Yoshi, too

(Bebop)
Great idea! Who needs a ninja clan?

(Bebop and Rocksteady)
No ninjas, no ninjas! Hahahahahaha!

(Shredder)
Idiots! There is a ninja clan!

(Bebop)
Hey, but you said-

(Shredder)
We will be the only ninja clan!
Stick with me and you'll have power beyond your dreams!

(Rocksteady)

Yay, all right! Long live the Shredder!

(Bebop, Rocksteady and Krang)
Long live the Shredder!

It's great that we'll soon be connected
With a ruler who'll be all-time adored

(Shredder)

Of course, quid pro quo, you're expected
To take certain duties on board

The future is littered with prizes
And though I'm the main addressee
The point that I must emphasize is
You won't get a bit without me!

So prepare for the coup of the century
Be prepared for the murkiest scam

Meticulous planning tenacity spanning
Decades of denial is simply why I'll
Be undisputed respected, saluted
And seen for the wonder I am

Yes, my foot and ambitions are bared-
Be prepared!

(Bebop, Rocksteady and Krang)
Yes, our foot and ambitions are bared-

(all four)
Be prepared! (evil laugh)
