Zomboss visits his old model train, dubbed "Big Spitball," in a gigantic train set that takes up a whole warehouse. Using the Big Spitball's zuclear-powered engine and shrink ray, Zomboss miniaturizes the buildings of Neighborville and adds them to the huge diorama!

He even shrinks down a building with Nate, Patrice, Crazy Dave, and some plants inside! Now the team and their plant pals need to reach the engine of the Big Spitball to unshrink themselves and save Neighborville!
