A month went by and I had succeeded in potty training the blue cow. Then, one morning, I woke up to find the blue cow at the foot of my bed sleeping! I realized that it was on my feet. "Get off!" I cried. The blue cow awakened with a start and fell off the bed. It mooed loudly. The circulation in my feet came back and I got out of bed. I had breakfast and took the blue cow to it's shed, but it still knew how to open doors.
