Ox
From Tardis Wiki, the free Doctor Who reference
Oxen were beasts of burden commonly used on Earth. Cameron Campbell once travelled in rural India and was disturbed by the fact he couldn't see even one skinny ox pulling farmers around in a cart. (PROSE: Ghosts of India)
The Thirteenth Doctor sent Graham O'Brien to collect the spit from an Ox. (TV: Demons of the Punjab)
