When you're with Geronimo Stilton, it's always a fabumouse adventure!
I was so excited for the relaxing, stress-free day I had planned. But nothing ever goes my way. I got a mysterimouse letter from an old friend asking for my help solving a case. There were giant footprints in Chocolate Hills, and whoever was creating them was ruining the forest. Could I help save the hills before it’s too late?
