Sense Sonnet - Acher

Toughie

The Rabbs fringe limbed tree frog - no more.
Toughie, the last known one, has died.
There are pictures of him galore.
His call - one record does provide.
Rescued by humans, he was brought
To a Zoo, receiving good care.
Tries were made, but Toughie was not
Able to mate with success there.
Finally, Toughie was the last
Of his tree frog kind known to be,
A star in the role he was cast -
Amphibian celebrity.

Toughie, the last such frog is gone.
Only his memory lives on.
