It's the hottest day of the year in Fine Forest! The Piggies build an ice machine for cold drinks, but Wilf, wanting it all to himself, accidentally causes a blizzard.

Dana wants to cheer Wilf up and asks the Piggies to find something that will make him happy. But Wilf takes advantage of their kindness and requests a honking vehicle - just to annoy everyone! When it breaks, Wilf is even more miserable.

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!
