The last thing Jack expected when he bungee-jumped at the fairground was to go plummeting right through the ground into the weird, wonderful Rooms... There he must face a series of puzzles and traps alongside a mysterious girl called Cally, in order for them to find their way home. Throw in a murderous polar bear, hundreds of tiny yet ferocious lions, some mind-blowing riddles, and get ready for a hilarious, helter-skelter adventure like no other!
