What is that?! What is that doof-doof-doof noise?
A cat? A mouse? A visitor in the house?

No, it’s something even furrier than a cat, even cuter than a mouse,
and much tinier than you and me.

It’s the three Doof-Doofs.

These sweet creatures have only one foot each to hop on. And each hop makes
a thumping doof-doof on the floor

Here is Solly Doof, the smart one, who is always thinking looooong and loud.

He uhhs and ahhs and doof-doofs all night long.
