This book was a great book and I recommend many others to read this book. One favorite part of the book was when Bugsy Wugsy's shirt got stuck on a stick and was hanging in mid-air at the top of a cliff! Geronimo was with her trying to save her. But then, a mountain lion showed up trying to get Bugsy Wugsy too. Geronimo Stilton was so afraid of the mountain lion that he screamed at the top of his lungs. Surprisingly, the mountain lion ran away!
