Superloo is a power-crazed toilet with an ego as big as a planet, a microchip that belongs to NASA and a mission to rescue his toilet ancestors from the past. All he needs now is a human helper - and then along comes Finn.
In this second adventure Superloo whisks Finn off to Roman Britain where the Emperor Hadrian is visiting his Wall. Conspiracies and plots are afoot involving gladiators, bears, very fierce British tribes and, of course, Hadrian's famous latrine. Fast and furious fun - and why has Finn got a pocketful of dormice?
