Welcome to Pocketville! This is a wonderful country, where puppies and kittens live, and Princess Amy helps them to meet the children who want to find a true friend. Then one day, her evil sister Ima sends Amy into the "real world", while Kate, an ordinary schoolgirl, goes to Pocketville to take her place. Now, with the help of a puppy Magica, she should continue the important work of Amy and prevent domineering Ima from taking the place of the princess.
