Monster Shapes

The mother asked Caleb,
“What shape is this?”
“That’s the shape of a MONSTER!”
Caleb did hiss.
“It’s red and it’s blue
And it has a forked tongue.
No toes or fingers,
But twenty-nine thumbs.
No nose on its face
But thirty-two eyes,
Three horns on its head
That vary in size.
It eats only the eggs
Of a goose or a pheasant.
The name of this monster –
A Cantankerous Crescent!”
“A crescent it is!”
The mother did say.
“Now what shape is this?
And don’t take all day.”
Caleb studied the picture
And tugged at his ear:
“A Squalidly Square-fiend
Is what we have here.
A Square-fiend is red
With yellowish dots.
Its long hair is tangled
And tied up in knots.
Aligning its gums
Are rows of sharp teeth.
It’s covered in fur,
But with spikes underneath.
When it hears babies cry,
It cackles with glee.”
“Enough,” laughed the mother.
“Now what shape do you see?”
“A yellow-tailed beast,
Its eyes pop in and out.
There’s short, wiry fur
On its belly and snout.
The claws on its fingers
Are twenty feet long.
It smells most atrocious.
 It’s fifty bears strong.
It lives in a nest
High up in a tree:
The Toxic Triangle
Of Tog-Tippani.”
“Triangle is right,”
The mother did sigh.
“So, how about this shape?
Let’s give it a try.”
“Aha!” said young Caleb.
“A rare find indeed.
It’s as mean as a bobcat
With ten times the speed.
With no arms or legs,
It rolls ‘cross the land,
Devouring creatures
On grass and on sand.
It’s camouflageable skin
Is its claim to fame.
Contemptible Circle-beast
Is this monster’s name.”
“All right,” said the mother,
“Our very last one.
Tell me about this shape
And then we are done.”
“My most favorite monster!”
Caleb did shout,
“The most ferocious and evil,
There isn’t a doubt.
An orange-ish monster
With lots of green stripes
Where its insides should be,
Instead it has pipes.
Its metallic skin is tougher than nails.
It eats children’s toes
And small kittens' tails.
It hasn’t a brain,
And it hasn’t a soul.
It’s the Rancid, Robotic,
Rectangular Troll.”
“A rectangle. Well done,”
The mother then said,
“And you’ve taken so long,
It’s now time for bed.”
