Description: Enter the world of Geronimo Stilton, where another funny adventure is always right around the corner. Each book is a fast-paced adventure with lively art and a unique format kids 7-10 will love. When my nephew, Benjamin, invited me to Career Day at his school, things did not turn out the way I expected. I caused a volcanic explosion, got tangled in the tunnel slide on the playground, and accidentally let the class's pet gecko out of its cage! Rat munching rattlesnakes -- how was I going to get myself out of this mess?
