The Digimon had several functions that allowed the owner to take care of the pet. The first icon is the status. The user can check the pet's age, weight, strength, hunger, and energy stats here. If a Digimon had no energy in its energy bar, it would be unable to link up and battle. The fifth Icon (the first on the bottom row) cleaned up the Digimon's droppings. Leaving droppings uncleaned for too long would cause the Digimon to become ill. Digimon could expire due to extreme hunger, illness, too many battles, or old age. The Digimon Mainframe is only viewable on the American version one pets.
