It's Them Monkey Pirates Again By Mark Skelton

Them Monkey Pirates are back--and this time they have promised to find Emily Jane's uncle. But they end up in the future instead. Can a robot called Julian and a very large banana help? Or will it all end in monkey mayhem and mischief? Aargh! Bananas and barnacles! This is another funny book starring many monkeys, a time-traveling wardrobe, and a very rude book fairy--readers have been warned!
