Little crossing eyes so cute they do beguile
And that little diamond head makes me smile
I stare at you in that petrie
I slice you half-way with a blade
Two heads grow - now that's so nifty
Now two I've made - a new one's made

Plana plana plana plana plana planarian
From one make four - from one make four
Reproducing's easy when you're growing parts from your seams
Tails, heads and more - tails, heads and more

I stare at Escher's print everyday
Don't know why they fascinate me so this way
Flatworms are like an addiction
With them I've formed quite a bond
I like to say tubelleria
And skim that pond - and skim that pond

Plana plana plana plana plana planarian
You glide real slow - you glide real slow
Females and males are a-sharing the same body
Conveniently - conveniently

Altho' they are just so slimy
They cling nicely in this rhymy
Worms so flat - looks like a flounder
Be less cuter if they're rounder

I'm not int'rested in earthworms
I don't really wanna know
I'll stick to platyhelminthes
They munch you know those roundworms so

Plana plana plana plana plana planarian
From one make four - from one make four
Like the way you're working altogether like you're a team
Tails, heads and more - tails, heads and more

Plana plana plana plana plana planarian
From one make four - then split once more
Splitting is so easy - pretty soon you become sixteen
With parts galore - with parts galore

Plana plana plana plana plana planarian
From one make four - from one make four
Reproducing's easy when you're growing parts from your seams
Tails, heads and more - tails, heads and more
