The people of the Kingdom of Klunkenhausen always believed they lived on a flat, square-shaped world. Their world view suddenly changed the day Royal Explorer Sir Harold Pudding revealed to King Lorenzo, Queen Penelope, and Princess Natalie von Klunkenhausen, "We don't live on a flat world after all!"

After realizing they may instead be living on the top side of a cube-shaped, six-sided planet, Princess Natalie joins her parents, Lilly her pet dog, Professor Copernicus Corona, and Sirs Pudding and Dudley Diggesalot on a journey to explore these five other mysterious lands. As these lands are located down very steep and scary ninety-degree angles from the edges of their kingdom, travel proves to be tricky and potentially dangerous.

Will the brave Klunkenhausen explorers find themselves sideways or even upside down on the five other sides of their cube-shaped planet? Also, what inhabitants or creatures might they encounter? Will they be friendly or scary? Will Princess Natalie do her homework and clean her room? Read on to find out!
