The two friends, Fox and Piglet, have found out about a new invention, where you put an empty bottle into a machine and get a beep back. They want to try and make their own machine. But it should be for full bottles and preferably with some cakes and sweets, too.
They build with great enthusiasm, but business does not go very well. Fortunately Cow comes along and saves the day.
The Beepomate is the ninth book about the cult characters Fox and Piglet!
