Garbage Dump Disaster: Geronimo Stilton

Moldy Mozzerella, what was that smell? It was my friend Hercule, and he needed my help. Someone was stealing ... garbage! A rascally rodent had been sneaking into the Recycling Plant and taking their trash. With the help of Flora, the plants owner, Hercule and I try to sniff the rat out of the stench. Can we find the thief before he runs away with all our trash?
