Ralph is probably the laziest rat in the world. However, he recently discovered he is the rightful heir of the Helvetio Kingdom and its Royal Storehouse of 10,000 cheeses and 500 varieties. Ralph is KING RAT (or so he believes). Now he has to travel to Switzerland to claim what’s his. A long journey from his boring town in deep America to the most refined cities in Europe. Besides hunger, exhaustion, predators, oceans, thieves, natural disasters, diseases... what could possibly go wrong?
