The third very funny story about the children at pirate school.

The children hide a stray dog on board, while Patagonia Clatterbottom, the head teacher, is plagued by school inspectors, who are not impressed by the lessons.

So, the children decide to sail the school away. The inspectors give chase, but the children fire on their boat and take it over - full marks for the lessons they have learnt about being pirates. And they're allowed to keep the dog!
