The Toad

Here is a tale to tell to rich relations:
There was a toad, a Calibanic monster,
In whose squat head ambition had ensconced her
Most bloated jewel, dear to highest stations.
He was received, though mottled as a lichen
In coat and character, because the creature
Croaked as the devil prompted him, or nature,
And said the right thing both in hall and kitchen.
To each he sang according to their liking,
And purred his flattery in the ear of Leisure,
Cringing attendance on the proud and wealthy.
One day a crane, with features of a Viking,
Swallowed him whole and did it with great pleasure:
His system needed such; toads kept him healthy.
