The very royal holiday

Finally. Holly, Anna and Pepino are on the Holy Moly Holiday. Their cruise ship has a racing car track and a kitten parlour and rollerblading in foam and a non-stop giant chocolate fountain! Even the annoying royal children with them can't spoil the fun. But then the ship falls off the Southern Edge of Earth into space! How will they get home? Suddenly, this holiday feels like a lot of hard work!
