#25: The Search for Sunken Treasure
Holey cheese, what an adventure! I was off to the Ratlápagos Islands with my family in search of a long-lost buried treasure. But oh, how I hate traveling! Being on a ship in the middle of the sea wasn't my idea of a "fabumouse" time. And I was beginning to suspect that we weren't the only ones searching for the treasure. . .

#26: The Mummy with No Name
Halloween and Egypt and mummies . . . oh, my! I admit it, I am a 'fraidy mouse. Halloween scares me out of my fur! But this Halloween, I was heading off on an adventure in one of my very favorite places: Egypt. I couldn't wait to see the sights and soak up some sun far away from New Mouse City. What I didn't realize was that Halloween is popular in Egypt, too -- with the mummies, that is!
