A king discovers that there is no money left in "the royalpurse" and panics to find a way to raise money for the royalpeople at the castle. Suggestions are given and it is finally decided that the castle will be opened to the public, with admission charged to those who enter. In order to draw people to the castle, ice cream, created by Dr. Potamus, is promised to each guest. The incompetent "royal chart-maker" creates a map to the castle and the ice cream is made for the anticipated guests. When the princes and princess of the castle find lines of people walking to their uncle's castle across town instead of their castle, they begin to worry. How were they going to get all those people to their castle before the ice cream melted? This book was entertaining and fun to read, as it provided plenty of dialogue between the unique characters. It was also neat to see how the children in the story were involved in making decisions for the castle. There was a great deal of sarcastic humor used in the story, which makes this story funny to older children as well as younger children. The colorful watercolor illustrations provided an action-packed visual image of the action that was taking place in the story.
