Pigs at the Picnic

 is a book in the Animal Ark book series, written by Lucy Daniels, which was first released in a unknown date.

Summary
Mandy and James are taking a two week working holiday for young volunteers. The project they have chosen is a working farm owned by a charitable trust, dedicated to preserving traditional farming methods and rare breeds of farm animal.

At the end of the two weeks there is an open air fundraising event scheduled, with a concert, guided tours and a buffet picnic planned. But, on the day, a local farmer with an axe to grind sabotages the event, releasing the pigs, who proceed to eat all the food prepared for the picnic!

Mandy and James must step in to round up the pigs - and somehow come up with some alternative food for the picnic - before the whole day is ruined!
