The Three Different Sizes of a Poem

i. Small

Bat
Louse
Rat
Mouse

ii. Medium

A mild koala
A loud goose
A wild impala
A proud moose

A slim bison
A tough lamb
A trim python
A rough ram

iii. Large

A crash of furiously elegant rotund rhinos
A squad of tremendously industrious spacious squid
A thunder of curiously relevant humongous hippos
A drift of stupendously luxurious porky pigs

A parade of hilariously dangerous elongated elephants
A colony of deliciously perceptible elasticated eagles
An army of precariously adventurous ample ants
A trumpet of suspiciously flexible beefed-up beagles

A nursery of resiliently consistent roomy racoons
A pod of amazingly expensive widened whales
A troop of brilliantly persistent bulbous baboons
A walk of blazingly extensive stretched out snails

A drove of arrogantly generous hefty hares
A labour of contagiously productive massive moles
A sleuth of extravagantly treacherous bulky bears
A cloud of outrageously destructive towering tadpoles
