GERONIMO STILTON Book 7: RED PIZZAS FOR A BLUE COUNT
Trap is in trouble! He calls Geronimo from Transratania, asking for help. When Thea, Benjamin and Geronimo get to Ratoff, every mouse in town is wearing and eating garlic --- and acting too scared to squeak when the travelers ask the way to Ratoff Castle.
The trio manages to find and sneak into the dark, eerie castle. They watch the count and countess drink (gasp!) blood! The three go undercover, working as servants, in order to rescue Trap. They must solve the castle's mysteries: Why do the inhabitants eat bugs and sleep hanging upside down? The truth surprises not only Geronimo and the gang, but also the reader!
