Patty lives with her Aunt Bat on a banana plantation in Jamaica. Unfortunately, as it`s such a small plantation, they`re having trouble keeping up with the competition, and Aunt Bat is worried they`ll have to sell up. Patty needs to think of an idea to turn things around, and fast! Inspiration comes to her as she`s digging into a chocolate banana special at her local ice-cream parlour. All she needs to do is invent a machine - a banana machine. Will Patty`s mechanical wizardry help the plantation out of its crisis? Or, like the bananas, are her ideas round the bend?
