Yertle

I have a turtle,
His name is Yurtle,

He's brown and black,
And striped on his back,

My dog tried to eat him,
But advice from Jim,

Said to give him a pan,
Of water to lay in,

A cool damp spot,
And lettuce - no rot,

So that is the story,
Not romantic nor gory,

Of my dear little turtle,
The turtle named Yertle.
