"Every mysterious fact is connected in surprising and sneaky ways. Follow a trail that slinks from facts about spy gadgets to facts about hidden toilets to facts about secret languages to facts about thieving cats. And there isn't just one trail through these facts. Sometimes your path branches, and you can choose to uncover a completely different (but still connected) part of Secret FACTopia! Where will your curiosity take you?"--
