Duck Tents

In a small backyard, by a squat stone fence, five little ducks pitch five duck tents.

The five little ducks are going camping! They can't wait for a day of fun at the fishing hole. In the evening they sit around the campfire and toast marshmallows. But just as they're about to snuggle up tight and drift off to sleep, they hear a scary noise. Whooo can it be?
