Preteen Donnie talking to Chong (the first spy-roach) in his lab:

(Maybe they're right. Maybe there is something wrong with me.
I just don't get how a world that makes such amazing things could be so dangerous.)

Look at this stuff
Isn't it neat?
Wouldn't you think my laboratory's complete?
Wouldn't you think I'm the turtle
The turtle who has everything?
Look down the tunnels
There's hidden potential
How many treasures are experimental?
Looking around here you think
Sure, he's got everything
I've got gadgets and gizmos a-plenty
I've got whozits and whatzits galore
You want thingamabobs?
I've got twenty!
But who cares?
No big deal
I want more

I wanna be where the humans are
I wanna see, wanna see them inventing
Walking around in those - what do you call 'em?
Oh - clothes!

Training your body, you don't get too far
Brains are what I wanna use more of
Learning a lot more of - what's that word again?
Science!

Up where they talk, up where it's fun
Up where they stay all day in the sun
Wandering free - wish I could be
Part of that world

What would I give if I could live out of these sewers?
What would I pay to spend a day warm on the sand?
Betcha on land they understand
Bet they don't make fun of their brothers
Bright young humans, sick of training
Ready to learn

And ready to know what the humans know
Ask 'em my questions and get some answers
What is propane and why does it - what's the word?
Burn?

When's it my turn?
Wouldn't I love, love to explore the surface up above?
Out of the sewers
Wish I could be
Part of that world

I swear to god that the next one will NOT be Donnie centered!
