Udo sat up rather eagerly.

"I'll try," he said. "Is there any particular action that goes with it?"

"I've never heard of any. I expect you ought to say it as if you meant it."

Udo sat up on his back paws, and, gesticulating freely with his right paw, declaimed:

"Bo, boll, bill, bole.
Wo, woll, will, wole."

He fixed his eyes on his paws, waiting for the transformation.

He waited.

And waited.

Nothing happened.
