A sudden whuff from the old heater startled everyone in the room.

The little toy train began to whuff every time the child wound it up.

The whuffs coming from the old radiator kept waking me up all night.

Every morning the old steam train whuffs as it pulls out of the station.

The collector displayed his newest whuffos on the shelf, each one more bizarre than the last.

Despite all the cheering from the crowd, the nervous whuffo stayed firmly on the ground instead of joining the jump.

The old chimney whuffed and scattered sparks across the roof.

The old bellows lay whuffing in the corner as the blacksmith worked.

I don't see whuffo we'd need so many chairs.

After rolling in the fallen leaves, the little terrier whuffled and then settled into a warm patch of sun.
