After marrying Auntie Sheep, Mr. Rat settled in Animalville and moved the headquarters of his company, Good, Inc. there. Next, he opened a housewares store. The Walkers' new uncle felt that although his new business made a tidy profit--as everyone needs brooms!--selling old, rare, unique and, consequently, expensive merchandise would create a much larger gain. As you probably guessed, he decided to open an antique store. Uncle Rat is a very experienced business person and usually doesn't need any assistance. Still, everybody knows that the Walkers have no peer in searching for outlandish items and rare souvenirs as well as solving puzzles. So the family accepted this fascinating challenge - to find the most beautiful items for Mr. Rat to sell at the first antique store in Animalville! Join the Walkers in this new adventure!
