Potato does tend to run around recklessly. Whenever I hear crashing and thumping from the next room, it's always Potato, running laps and smashing into the walls and pigloos. It's amazing he can move so fast.
Apparently he can move even faster than he can react, since I saw him do this one time. He ran for the food and tried to go around Fuzzy by going through the pigloo. But the pigloo doesn't have a back door.
