Sense Sonnet - Pumper

Glass Frog

Called a glass frog, I got the name
Because my belly be see through,
Clearly a for sure claim to fame,
I do show what's inside, I do.
My gastrointestinal tract
Is visible and can be seen
From underneath, and that's a fact.
My upper back is a lime green.
I am small, a quarter coin size,
And live in rain forest terrain.
I can be heard to vocalize,
If you trespass in my domain.

A tummy ache does settle in,
If you get under my clear skin.
