Supplementary Notes>>>

All items of Cat Island are divided into three categories: vegetation, masonry, and water. When each item is combined into a high-level item, it is based on the classification of the item. For example, grass can only be a shrub, not a sailboat   The category of items determines where they should be placed. Cat Island is surrounded by the sea, with land in the middle. Vegetation, bricks and stones can only be placed on land, and aquatic objects can only be placed in the blue sea. The specific classification of the objects can be intuitively known through the color of the lines: grass and trees green, brick and stone coffee color, and other colors are blue. Here is a wonderful flower, that is, crystal belongs to water..
