The Schmoo was a loveable creature, really.
Laid eggs, gave milk and died of sheer ecstasy when looked at with hunger.
The Schmoo loved to be eaten. It could taste like any food you desire.
Schmoo hide, cut thin, made fine leather.
Even Schmoo whiskers made excellent toothpicks.

In essence, the Schmoo supplied all of the world's wants.
