The Cloud Cow spends the majority of it’s time majestically floating across the sky, occasionally descending to earth to graze high altitude vegetation. Due to the high content of vegetable matter in it’s diet, the Cloud Cow is known for it’s incredible ability to flatulate, through which it is known as the producer of most of the Earths clouds. Usually producing clouds of the fluffy white cumulus variety, it is thought that other types of clouds may be produced by the Cloud Cows depending on their recent diet. It is well documented that Cloud Cows produce large black thunder clouds when suffering from indigestion, thus being responsible for both the cloud, and the accompanying sound of thunder.
