A game for the ZX Spectrum in which you had to pretend to be an animal, and wander around the world finding food and avoiding predators. You could play as a hawk, lion, robin, mouse, fly or butterfly. Since baby animals are very vulnerable, you started the game as a young adult. Aging was built into the game - it was harder for old animals to hunt their prey. One game could take quite a long time, but it had the great advantage that as it was turn-based, you could start a game before school and leave the computer on until you got home.
