Digimon Twin L & R
A Digimon digivolves into Burpmon if its weight reaches 80G. Burpmon is constantly hungry, but almost no amount of food sates it. It also refuses training of any kind. It infects any other Digimon it comes in contact with, turning them into Burpmon also. It changes back to its original form once its weight drops below 80G. All the while, it beeps non-stop for food.
