Very lazy. Just eats and sleeps. As its rotund bulk builds, it becomes steadily more slothful.
Will eat anything, even if the food happens to be a little moldy. It never gets an upset stomach.
What sounds like its cry may ac tually be its snores or the rumblings of its hungry belly.
Its stomach's di gestive juices can dissolve any kind of poison. It can even eat things off the ground.
This POKéMON's stomach is so strong, even eating moldy or rotten food will not affect it.
