Suzy is surprised to find a grumpy troll building a railway through her house - especially when a gigantic steam train crashes into her hallway! This is the Impossible Postal Express, the trusty delivery service of the Union of Impossible Places, and Suzy becomes its newest recruit. And with her cursed first package, an Impossible adventure begins. Welcome to the Impossible Places... Where there's fuzzics not physics, where adventure meets magic and where the journey will never, ever take you where you expect it to.
