Tales from Sty-Pen: Swerlie-Wherlie and Butts the Goat

Swerlie-Wherlie, the adventurous piglet, is exploring a quarry when he slips and is helped by Butts the Goat.
Butts offers to show him his secret place – deep underground.
They find a friend of Swerlie-Wherlie, Shep the sheepdog, locked in a small room in one of the underground passages.
Trying to escape from the humans who had locked him in, they fall into a tunnel and get lost.
They are saved by the sudden appearance of Izzzzzabella the grass snake, another friend of Swerlie-Wherlie who knows a way out but first they must try and rescue Shep.
They are too late. Shep was not where they had left him.
Izzzzzabella knows of a short cut that would take them to where Shep might be.
Unfortunately, they got there just as Shep is being taken away.
Swerlie-Wherlie had an idea that might save Shep but only if Butts can do what goats are famous for.
Meanwhile, Scratch the farm cat, has upset Cockie the Cockerel because of the way he had treated Donald the duckling.
As always, Cockie has a way of doing things his way.
