Rulers are stick blocks that are found in Donkey Kong 64. Like most toy enemies, they are found only in Frantic Factory. They can only be encountered in the Toy Monster's area, and therefore only Chunky Kong can fight them. They have no means of attack other than approaching Chunky and touching him. They have several shapes in their bodies, which include a green triangle, a blue rectangle, a red star, and a purple circle.
