The singular is obviously "aurochs", seeing how it is cognate with English "ox". Accordingly, the only reasonable plural form is, of course, "aurochsen", seeing how "ox" still uses the Saxon plural form "oxen" even in Modern English.

The auroch will cautiously proceed to eat the clover. It is recommended to get as close as possible before right clicking the aurochs. Next, take your bucket and right click on the aurochs to milk it. Each Aurochs can only be milked once (every 5 minutes?).
