Every animal in the farmyard is looking forward to the Chicken Sisters' party. They've put Cockerel in charge of invitations. As he goes around the farmyard Cockerel thinks that Duck is too wet, Cow is too slobbery, Dog is too flea-ridden and Pig is too muddy. Sorry but you're not invited, we're having a neat party for tidy animals, says Cockerel in a snooty voice. Cockerel goes home, has a bubble bath, polishes his beak and combs his feathers. He's very happy when he looks in the mirror, but the Chicken sisters are not happy when they find out what he's done. They carefully work out a plan to teach him and lesson - and the plan works out very neatly indeed!
