Furon creatures/monsters were supposed to be featured in the first game. They can be seen in several different forms in concept art. They were supposed to be unlocked very early and the game and besides the concept art titled The Barnyard, they are never featured. They seem to be controlled by Crypto, as they are often positioned next or by him. In one of the images, you can see one of them swalloing a school bus whole, indicitating children were also in the game. One can also be seen attacking a human aircraft. They have several eyes and legs, one having eight eyes.
