Penny continues to sing as her eyes sweep the area probing for weakness in security and opportunity. Penny notes almost immediately that this wasn't simply a school but a prison of sorts.
"Hmm this will require study" she thinks as she keeps up the persona of the annoying tough girl.
Penny knows that if she's been sent here then with her record being what it is this facility must have hidden layers of security. 

[B]"They say they're gonna kill me
If i look at you once more.
Pissed in my hammock yesterday,
So I'll sleep on the floor

I'd be under the sea,
but you hold me above.

They put glass on my sandals,
So my feet would bleed all day,
And they forced me to wear them,
Or they said they'd make you pay

I'd be under the sea,
but you hold me above.
'Cos you're the man i love"[/B] 

Penny knows she'll need to keep her body in good shape so she'll join all the physical activities she can and volunteer for kitchen duty to assure she receives enough calories to continue her efforts for freedom.
