Another classic from Russell Hoban and Quentin Blake, featuring a jam-powered frog and an eccentric headmistress ... as nutty and compulsive as ever.

A Russell Hoban and Quentin Blake classic, and a brilliant companion volume to How Tom Beat Captain Najork and His Hired Sportsmen, this is the story of Tom who invents a jam-powered frog. Fooling around as he loves to do, Tom takes his Aunt Bundlejoy Cosysweet out on the frog out for a spin. When Captain Najork sees them hopping past his window, he and his hired sportsmen jump into their pedal-powered snake and set off in hot pursuit. Events, adventure and sheer craziness conspire to bring Tom and the Captain together at the local girls' boarding school, where Aunt Fidget Wonkham-Strong Najork is in the middle of a best-of-three arm-wrestling contest against the Headmistress... A rip-roaring adventure guaranteed to keep the pages turning and the laughs bouncing off the ceiling!
