"Cows fly like clouds but they are never completely successful.
They just fly in circles around a target for as long as they can. That's the reason why it's impossible to predict what their position will be exactly at any point. They have to keep changing their direction to keep track of their target.
What's interesting is that cows fly like a tornado that is heading straight towards the target. This is because of the wind speed.
This is what they do in their world:
The cow is spinning around. It is trying to keep its head below the clouds. It is looking around to see what is going on around it. As the cow spins around it does a 180 degree turn. It changes its direction. And then it changes its direction again. This process continues forever.
A tornado with no wind."
