In Carnivores, Carnivores 2, and Carnivores Ice Age, the images are used to denote the clickable areas in menus. The unclickable regions have a value of 0x00 (null), with each clickable area having a value incremented by one from the previous area (so, for example, the first area has a value of 0x01, the second a value of 0x02, and so forth). Each image is 400x300 pixels in size and each file is 120,000 bytes long. The files are located in \HUNTDAT\MENU.
In Carnivores: Dinosaur Hunter, the images are used for cloud shadow maps. Each image is 128x128 pixels in size and each file is 16,384 bytes (16 kibibytes) in size. The files are located in \textures\sky.
