A beast with strong jaws,
Ferocious it's bight.

Most mammals, they run!
Eyes showing their fright!

They're hard to get rid of,
They're really persistent!

Most people who have 'em,
they call an assistant!

They steal all their food.
They hide in the mud,

Then when you walk past,
They suck out your blood!

They're black with red eyes,
With strong, hairy feet.

Their pinchers we hate!
Although they are beat,

With rather simple means.
Defeated with ease!

This beast that I speak of,
We know them as fleas!
