Tom likes fooling around and is rather good at it, much to the annoyance of his Aunt Fidget Wonkham-Strong. So one day this fearsome lady decides to teach Tom a lesson and summons Captain Najork and his Hired Sportsmen to play womble, muck and sneedball. Can it possibly end well for all concerned?

Captain Najork has never quite got over the time that Tom beat him and his hired sportsmen at womble, muck and sneedball, so when he sees Tom hurtle past his window in a two-seater jam powered frog, he sets off in hot pursuit.
