The Piggies are called on multiple missions and decide to split up. They soon realise they were all working on Fiona's surprise birthday! Nothing is ready… Mission impossible? Not if they join forces!

The Piggies are building a model of Fine Forest, and each house must match the real one. But when a drop of gold paint lands on Fiona's yurt model, Wilf is convinced it hides treasure. He will do whatever it takes to get the yurt - no matter the risk!
