Which of the Pickwick Triplets Did It

Three little babes in their bassinets
Angelic little triplets or triple threats?
They might have fooled the others, but they won't fool me
It's time to give these teething, seething three
The third degree

Which of the Pickwick triplets did it?
Who of the crew could commit this crime?
Might a little brat make a mommy go splat?
It's a story pretty gory for a nursery rhyme
Which of the Pickwick triplets did it?
Which of the spawn had the brawn to kill?
Will a baby get tried for matricide?
Coochie-coochie-coo, time for you or you or you to admit it
So quick as a whip gotta pick which Pickwick triplеt did it

Penelope in pink surе is making quite a stink
Is she trying to throw me off the scent?
Though she bats her little eyes, is she a killer in disguise
With a diaper full of criminal intent?

Preening Patrick is pernicious with an appetite so vicious
He would bite the hand that feeds him with a sneer
But could that rotten tot be behind this evil plot
Baby-stepping towards a murderous career?

Pouty little Paco's looking coy, but he's a bad, bad boy
Could Paco's passion prove apocalyptic?
With his paci' and his rattle, did this pisher go to battle
Proving he's the perp amidst this Pickwick triptych?

In this picaresque puzzle of the Pickwick pack
Will a lighthouse shed some light
On which kid gave ol' mom a whack?
There's an infant to indict
I'll book this little crook tonight
But

Which of the Pickwick triplets did it?
Who of the crew would commit this crime?
Which little brat made mommy go splat?
Which crib, which sib will be doing hard time?
Which of the Pickwick triplets did it?
Which little putz had the guts to kill?
Like a forensic pediatrician, I'll complete this inquisition
I will name the neonatal from the cradle that proved fatal
I will find the perpetrator who did murder to their mater
Or
Coochie-coochie-coo
What if none of it is true?
Has my inspection been too cursory
Should I look outside this nursery?

What if none of the Pickwick triplets did it?
Who'd have had a menacing motive and hid it?
Who? Who? Who? Well
I pick you!
