A digital pet (also known as a virtual pet or artificial pet is a type of artificial human companion. They are usually kept for companionship or enjoyment. People may keep a digital pet in lieu of a real pet. Digital pets can be "simulations of real animals, as in the Petz series" or "fantasy ones like the Tamagotchi". Unlike biological simulations, the pet does not usually reproduce. They generally do not die. In Dig a-Dig Pukka (Kokohore! Pukka: Dig a-Dig Pukka) the player controls a miner robotic pet that will explore the lands searching for rare minerals and gems. In his jobs he will be rewarded by his founds with money that the player can use to buy new objects and tools.
