One day, my friends and I, Geronimo Stilton, made an amazing discovery. We found a huge oyster with an enormouse pearl inside! I was so excited about this extremely rare, precious pearl that I wrote a special feature about it in The Rodent’s Gazette. That article attracted lots of attention both good and bad! The enormouse pearl was in danger of being stolen. Would my friends and I be able to protect it?
