That's How We Don't Roll

[deckardcanine]

No earthly life has wheels for feet,
But if some did, would that be neat?
It’s not as easy as it sounds.
Consider all the unpaved grounds.
An animal could smooth its way,
But would the effort really pay?
The wheels could help one move real fast,
And trips and limps would long be past.
To climb a hill’s another matter;
One’s terrain must stay much flatter.
Furthermore, what body part
Is semi-sep’rate from the start?
Good luck in getting wheels that work
To come by nature; what a quirk.
In short, we’ll prob’ly never meet
A specimen with wheels for feet.
