A mule is a type of domesticated land mammal, the offspring of a male donkey and a female horse. Mules exhibit the patience and endurance of donkeys, and the strength of horses, making them suitable as pack animals for land expeditions, or working in agriculture to pull plows and loads.
Adventures with mules
In 1936, Indiana Jones traveled to Peru to find the Temple of the Chachapoyan Warriors. His expedition included several mules to carry supplies through the jungles. Some time after spotting Mount Shubet, Barranca tied one off one the mules as they neared their destination.
Jones fled Nazis through the streets of Rome on a mule-driven wagon in 1941. He eventually abandoned the mule when they reached a hilltop and chose instead to offload and mount a block of ice down the other side.
