The cow star of Gas is the most pest that we have seen in a long time. From their hindquarters emitted decaying gases, which if not collected, will contaminate the planet and charge the ozone layer. You know what your mission is.
We do not know what the cows on the farm have eaten, but now they produce milk in industrial quantities. As a farmer worried about your economy, your duty is to milk them in a hurry and sell it as soon as possible. Luck!
