Geronimo Stiltonoot and his family are off to find a cure for Grandma Ratrock's aches and pains.She's heard that a remedy hides in Cheesy-La, a legendary valley that Geronimo isn't even sure exists. Little does he know that getting there will be an adventure among geysers,volcanoes and rivers of molten lava.
